We've provided a Qwiic connector to connect to the I²C data lines easily, but you will also need to connect to two additional lines. This board is tiny, measuring 25.4 mm x 12.7 mm, which means it will fit nicely on your finger without all the bulk. The MAX30101 does all the sensing by utilizing its internal LEDs to bounce light off the arteries and arterioles in your finger's subcutaneous layer and sensing how much light is absorbed with its photodetectors. This is known as photoplethysmography. This data is passed onto and analyzed by the MAX32664, which applies its algorithms to determine heart rate and blood oxygen saturation (SpO2). SpO2 results are reported as the percentage of hemoglobin that is saturated with oxygen. It also provides useful information such as the sensor's confidence in its reporting and a handy finger detection data point. To get the most out of the sensor, Sparkfun has written an Arduino Library to make it easy to adjust all the possible configurations. Features SparkFun Pulse Oximeter and Heart Rate Sensor MAX30101 and MAX32664 sensor and sensor hub Qwiic connectors for power and I²C interface I²C Address: 0x55 MAX30101 - Pulse Oximeter and Heart-Rate Sensor Heart-Rate Monitor and Pulse Oximeter Sensor in LED Reflective Solution Integrated Cover Glass for Optimal, Robust Performance Ultra-Low Power Operation for Mobile Devices Fast Data Output Capability Robust Motion Artifact Resilience MAX32664 - Ultra-Low Power Biometric Sensor Hub Biometric Sensor Hub Solution Finger-Based Algorithms Measure Pulse Heart Rate and Pulse Blood Oxygenation Saturation (SpO2) Both Raw and processed data are available.

The SparkFun Qwiic Adapter provides the perfect means to make any old I²C board into a Qwiic-enabled board. This adapter breaks out the I²C pins from the Qwiic connectors to pins that you can easily solder with your favorite I²C-enabled device. The Qwiic Adapter has two Qwiic connection ports, all on the same I²C bus. Four plated through holes are broken out for SCL, SDA, 3.3V and GND. These pins can be used to convert an old I²C-enabled device into a Qwiic-enabled board. Features 2x Qwiic Connection Ports Broken-out I²C Pins
The Sparkfun Qwiic GPIO is an I²C device based around the TCA9534 I/O Expander IC from Texas Instruments. The board adds eight IO pins that you can read and write just like any other digital pin on your controller. The details of the I²C interface have been taken care of in an Arduino library so you can call functions similar to Arduino's pinMode and digitalWrite, allowing you to focus on your creation! The TCA9534's pins are broken out to easy-to-use latch terminals; never screw another wire into place! The terminals are relatively roomy themselves, so feel free to latch multiple wires into a ground or power terminal. With three customizable address jumpers, you can have up to eight Qwiic GPIO boards connected on a single bus allowing upwards of 64 additional GPIO pins! The default I²C is 0x27 and can be changed by adjusting the jumpers on the board's back. Features Eight Configurable GPIO Pins Available I²C Address: 0x27 (Default) Hardware address pins allow up to eight boards on a single bus Input Polarity Inversion Register Control each I/O pin individually or all at once Open-Drain Active-Low Interrupt Output 2x Qwiic Connectors Dimensions: 60.96 x 38.10 mm
The MLX90640 SparkFun IR Array Breakout features a 32×24 array of thermopile sensors generating, in essence, a low resolution thermal imaging camera. With this breakout you can observe surface temperatures from a decent distance away with an accuracy of ±1.5°C (best case). This board communicates via I²C using the Qwiic system developed by Sparkfun, which makes it easier to operate the breakout. However, there are still 0.1'-spaced pins in case you favour using a breadboard.
The SparkFun Qwiic connect system is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and helps you avoid errors. All Qwiic-enabled boards use a common 1 mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections help you connect everything correctly.
This specific IR Array Breakout provides a 110°×75° field of view with a temperature measurement range of -40~300°C. The MLX90640 IR Array has pull up resistors attached to the I²C bus; both can be removed by cutting the traces on the corresponding jumpers on the back of the board. Please be aware that the MLX90640 requires complex calculations by the host platform so a regular Arduino Uno (or equivalent) doesn't have enough RAM or flash to complete the complex computations required to turn the raw pixel data into temperature data. You will need a microcontroller with 20,000 bytes or more of RAM.
The Qwiic Mux also has eight configurable addresses of its own, allowing for up to 64 I²C buses on a connection. To make it even easier to use this multiplexer, all communication is enacted exclusively via I²C, utilizing our handy Qwiic system. The Qwiic Mux also allows you to change the last three bits of the address byte, allowing for eight jumper selectable addresses if you happen to need to put more than one Qwiic Mux Breakout on the same I²C port. The address can be changed by adding solder to any of the three ADR jumpers. Each SparkFun Qwiic Mux Breakout operates between 1.65 V and 5.5 V, making it ideal for all of the Qwiic boards we produce in house.
The SparkFun Qwiic OpenLog is the smarter and better looking cousin to the extremely popular OpenLog but now we've ported the original serial based interface to I²C! Thanks to the added Qwiic connectors, you can daisy chain multiple I²C devices and log them all without taking up your serial port. The Qwiic OpenLog can store, or 'log', huge amounts of serial data and act as a black box of sorts to store all the data that your project generates, for scientific or debugging purposes. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1'-spaced pins in case you prefer to use a breadboard. Like its predecessor, the SparkFun Qwiic OpenLog runs off of an onboard ATmega328, running at 16 MHz thanks to the onboard resonator. The ATmega328 has been sure to feature the Optiboot bootloader loaded, which allows the OpenLog to be compatible with the “Arduino Uno” board setting in the Arduino IDE. It is important to be aware that the Qwiic OpenLog draws approximately 2 mA-6 mA in idle (nothing to record) mode, however, during a full record the OpenLog can draw 20 mA to 23 mA depending on the microSD card being used. The Qwiic OpenLog also supports clock stretching, which means it performs even better than the original and will record data up to 20,000 bytes per second at 400 kHz. As the receive buffer fills up this OpenLog will hold the clock line, letting the master know that it is busy. Once the Qwiic OpenLog is finished with a task, it releases the clock thus allowing the data to continue flowing without corruption. For even better performance the OpenLog Artemis is the tool you need, featuring logging speeds up to 500000 bps. Features Continuous data logging at 20,000 bytes per second without corruption Compatible with high speed 400 kHz I²C Compatible with 64 MB to 32 GB microSD cards (FAT16 or FAT32) Preloaded Uno bootloader so upgrading the firmware is as easy as loading a new sketch Valid I²C Addresses: 0x08 to 0x77 2x Qwiic Connectors Downloads Schematic Eagle Files Hookup Guide Arduino Library GitHub
The Qwiic pHAT connects the I²C bus (GND, 3.3V, SDA, and SCL) on your Raspberry Pi to an array of Qwiic connectors on the HAT. Since the Qwiic system allows for daisy-chaining boards with different addresses, you can stack as many sensors as you’d like to create a tower of sensing power! The Qwiic pHAT V2.0 has four Qwiic connect ports (two on its side and two vertical), all on the same I²C bus. We've also made sure to add a simple 5V screw terminal to power boards that may need more than 3.3V and a general-purpose button (with the option to shut down the Pi with a script). Also updated, the mounting holes found on the board are now spaced to accommodate the typical Qwiic board dimension of 1.0' x 1.0'. This HAT is compatible with any Raspberry Pi that utilizes the standard 2x20 GPIO header and the NVIDIA Jetson Nano and Google Coral. Features 4 x Qwiic Connection Ports 1 x 5V Tolerant Screw Terminal 1 x General Purpose Button HAT-compatible 40-pin Female Header
This tiny little board does all of the neat Arduino tricks that you're familiar with: nine channels of 10-bit ADC, five PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx. Running at 5 V and 16 MHz, this board will remind you a lot of your other favourite Arduino-compatible boards, but this little guy can go just about anywhere. There is a voltage regulator on board so it can accept voltage up to 6 VDC. If you're supplying unregulated power to the board, be sure to connect to the 'RAW' pin on not VCC.
The reset button's benefit is to quickly reset the board or place it into bootloader mode without the need to take out a piece of the jumper wire. The USB micro-b connector has been replaced with the USB type C connector.
The through-hole pads have castellated edges for each pin to add a lower profile in your projects should you decide to build it into another assembly during production. Finally, a Qwiic connector is populated on the board's bottom to add Qwiic enabled I²C devices to your projects easily!

Plug a reader into the headers, use a Qwiic cable, scan your 125kHz ID tag, and the unique 32-bit ID will be shown on the screen. The unit comes with a read LED and buzzer, but don't worry, there is a jumper you can cut to disable the buzzer if you want. Utilizing SparkFun's handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins if you prefer to use a breadboard.
Utilizing the onboard ATtiny84A, the Qwiic RFID takes the six byte ID tag of your 125kHz RFID card, attaches a timestamp to it, and puts it onto a stack that holds up to 20 unique RFID scans at a time. This information is easy to get at with some simple I²C commands.
The SparkFun RP2040 mikroBUS Development Board is a low-cost, high performance platform with flexible digital interfaces featuring the Raspberry Pi Foundation's RP2040 microcontroller. Besides the Thing Plus or Feather PTH pin layout, the board also includes a microSD card slot, 16 MB (128 Mbit) flash memory, a JST single cell battery connector (with a charging circuit and fuel gauge sensor), an addressable WS2812 RGB LED, JTAG PTH pins, four (4-40 screw) mounting holes, our signature Qwiic connectors, and a mikroBUS socket. The mikroBUS standard was developed by MikroElektronika. Similar to Qwiic and MicroMod interfaces, the mikroBUS socket provides a standardized connection for add-on Click boards to be attached to a development board and is comprised of a pair of 8-pin female headers with a standardized pin configuration. The pins consist of three groups of communications pins (SPI, UART and I²C), six additional pins (PWM, Interrupt, Analog input, Reset and Chip select), and two power groups (3.3 V and 5 V). The RP2040 is supported with both C/C++ and MicroPython cross-platform development environments, including easy access to runtime debugging.

IR Receiver Diode: This simple IR receiver will detect an IR signal coming from a standard IR remote control or the IR diode included in the kit.
Resistor 1.0M Ohm 1/4 Watt PTH: Two 1/4 Watt, +/- 5% tolerance PTH resistors. Commonly used in breadboards and perf boards. The large resistor helps dampen any voltage spikes when using the large piezo vibration sensor with a microcontroller.
Resistor 10K Ohm 1/4 Watt PTH – 20 pack (Thick Leads): 1/4 Watt, +/- 5% tolerance PTH resistors. Commonly used in breadboards and perf boards, these 10KΩ resistors make excellent pullups, pulldowns, and current limiters.
Resistor 330 Ohm 1/4 Watt PTH – 20 pack (Thick Leads): 1/4 Watt +/- 5% tolerance PTH resistors. Commonly used in breadboards and perf boards, these 330Ω resistors make excellent current-limiting resistors for LEDs.
SparkFun 9DoF IMU Breakout – ISM330DHCX, MMC5983MA (Qwiic): This breakout board includes a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer. Connect this board over I2C using a Qwiic cable or solder wires or headers to the SPI pins to get started using one of the three sensors or using all three together to determine 3D orientation.
SparkFun Atmospheric Sensor Breakout – BME280 (Qwiic): The SparkFun BME280 Atmospheric Sensor Breakout is an easy way to measure barometric pressure, humidity, and temperature readings, all without taking up too much space.
SparkFun Indoor Air Quality Sensor – ENS160 (Qwiic): The SparkFun ENS160 Indoor Air Quality Sensor is a digital multi-gas sensor solution with four sensor elements that can be used in a wide range of applications including building automation, smart home, and HVAC.
SparkFun Capacitive Touch Slider – CAP1203 (Qwiic): This little board acts great as a non-mechanical button. Use the three pads on the board or connect your own input for a great touch button or slider with no moving parts.
Flexible Qwiic Cable (100 mm): Use these to connect up to four Qwiic boards in your kit.
RGB and Gesture Sensor (APDS-9960): This board does a little bit of everything. You can measure ambient light or color as well as detect proximity and do gesture sensing all over I2C.
Soil Moisture Sensor (with screw terminals): Ever wonder if your plant needs water? This sensor outputs an analog signal based on the resistance of the soil. Since water is conductive, the soil water content will be reflected in the soil resistance.
Sound Detector: Ever need to know if there is noise in an area? This board will not only tell you, but it will also output amplitude as well as the full audio signal.
Break Away Headers (Straight): Solder these pins to any of the breakouts to prototype on a breadboard. You'll want to solder these to boards that do not have Qwiic connectors such as the gesture sensor and sound detector.
Thanks to its I²C capabilities, this PWM HAT saves the Raspberry Pi's GPIO pins, allowing you to use them for other purposes. The Servo pHAT also adds a serial terminal connection, which will allow you to bring up a Raspberry Pi without having to hook it up to a monitor and keyboard. We have provided a Qwiic connector for easy interfacing with the I²C bus using the Qwiic system and a 4-pin header to connect to the Sphero RVR. Power to the SparkFun Servo pHAT can be supplied through a USB-C connector. This will power either the servo motors only or power the servo motors and the Raspberry Pi that is connected to the HAT. We switched to USB-C to allow you to bring more current to your servos than ever before. This USB-C connector can also hook up the Pi via serial port connection to avoid having to use a monitor and keyboard for setting up the Pi. To supply power only to the servo power rail (and not the Pi's 5V power rail), you need to cut a small trace on the isolation jumper. Doing this allows you to drive heavier loads coming from multiple or larger servos. We've even added power protection circuits to the design to avoid damage to power sources. Each of this pHAT's 16 servo motor pin headers has been spaced out to the standard 3-pin servo pinout (ground, 5V, signal) to make it easier to attach your servo motors. The Servo pHAT is the same size and form factor as a Raspberry Pi Zero and Zero W, but it can also operate with a regular Raspberry Pi.

SPIDriver shows you what’s happening on the SPI bus in real time, so no more guessing about the bus state. Its purpose is to make understanding the functioning of SPI hardware more intuitive. It's useful if you're into debugging hardware or simply introduce a class to SPI for the first time.
You can directly control LEDs and LCD displays just by having SPIDriver and you won't have to deal with microcontrollers. It's also a useful tool for examining, backing up and cloning an SPI flash as well as reading and writing SPI flash in circuit.
SPIDriver is also applicable if you want to drive, test and evaluate different displays.
With the help of current and voltage monitoring you'll be able to detect electrical problems at early stages. Thanks to the included color coded wires you can hook SPIDriver up without much effort; no pinout diagram required. It includes 3.3 V and 5 V supplies for your device, plus a high-side current meter.
SPIDriver comes with software to control it from:
a GUI
the command-line
