  • SparkFun Pulse Oximeter and Heart Rate Sensor - MAX30101 & MAX32664 (Qwiic) - Elektor

    SparkFun SparkFun Pulse Oximeter and Heart Rate Sensor - MAX30101 & MAX32664 (Qwiic)

    Out of stock

    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.

  • SparkFun Qwiic GPIO - Elektor

    SparkFun SparkFun Qwiic GPIO

    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

  •  -27% SparkFun Qwiic IR Array MLX90640 Breakout - Elektor

    SparkFun SparkFun Qwiic IR Array MLX90640 Breakout

    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.

  • SparkFun Qwiic OpenLog - Elektor

    SparkFun SparkFun Qwiic OpenLog

    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

  • SparkFun Qwiic pHAT v2.0 for Raspberry Pi - Elektor

    SparkFun SparkFun Qwiic pHAT v2.0 for Raspberry Pi

    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

  • SparkFun Servo pHAT for Raspberry Pi - Elektor

    SparkFun SparkFun Servo pHAT for Raspberry Pi

    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. Features 16 PWM channels, controllable over I²C Qwiic connector 4-pin RVR header for connection to Sphero RVR USB-C connector 40-pin GPIO header for connection to Raspberry Pi CH340C USB Serial SOIC16 Updated logic level conversion circuitry Power protection circuits
