The MicroMod DIY Carrier Kit includes five M.2 connectors (4.2mm height), screws, and standoffs so that you can get all the special parts you may need to make your own carrier board. MicroMod uses the standard M.2 connector. This is the same connector found on modern motherboards and laptops. There are various locations for the plastic ‘key’ on the M.2 connector to prevent a user from inserting an incompatible device. The MicroMod standard uses the ‘E’ key and further modifies the M.2 standard by moving the mounting screw 4mm to the side. The ‘E’ key is fairly common so a user could insert an M.2 compatible Wifi module. Still, because the screw mount doesn’t align, the user would not secure an incompatible device into a MicroMod carrier board. Features 5x Machine Screws Phillips Head #0 (but #00 to #1 works) Thread: M2.5 Length: 3 mm 5x SMD Reflow Compatible Standoffs Thread: M2.5 x 0.4 Height: 2.5 mm 5x M.2 MicroMod Connectors Key: E Height: 4.2 mm Pin count: 67 Pitch: 0.5 mm

Voice recognition, always-on voice commands, gesture, or image recognition are possible with TensorFlow applications. The cloud is impressively robust, but all-the-time connection requires power and connectivity that may not be available. Edge computing handles discrete tasks such as determining if someone said 'yes' and responds accordingly. The audio analysis is done on the MicroMod combination rather than on the web. This dramatically reduces costs and complexity while limiting potential data privacy leaks. This board features two MEMS microphones (one with a PDM interface, one with an I²S interface), an ST LIS2DH12 3-axis accelerometer, a connector to interface to a camera (sold separately), and a Qwiic connector.

The Power Delivery Board uses a standalone controller to negotiate with the power adapters and switch to a higher voltage other than just 5V. This uses the same power adapter for different projects rather than relying on multiple power adapters to provide different output; it can deliver the board as part of SparkFun’s Qwiic connect system, so you won’t have to do any soldering to figure out how things are oriented. The SparkFun Power Delivery Board takes advantage of the power delivery standard using a standalone controller from STMicroelectronics, the STUSB4500. The STUSB4500 is a USB power delivery controller that addresses sink devices. It implements a proprietary algorithm to negotiate a power delivery contract with a source (i.e. a power delivery wall wart or power adapter) without the need for an external microcontroller. However, you will need a microcontroller to configure the board. PDO profiles are configured in an integrated non-volatile memory. The controller does all the heavy lifting of power negotiation and provides an easy way to configure over I²C. To configure the board, you will need an I²C bus. The Qwiic system makes it easy to connect the Power Delivery board to a microcontroller. Depending on your application, you can also connect to the I²C bus via the plated through SDA and SCL holes. Features Input and output voltage range of 5-20V Output current up to 5A Three configurable power delivery profiles Auto-run Type-C™ and USB PD sink controller Certified USB Type-C™ rev 1.2 and USB PD rev 2.0 (TID #1000133) Integrated VBUS voltage monitoring Integrated VBUS switch gate drivers (PMOS)

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 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

QRD1114 Optical Detector/Phototransistor: An all-in-one infrared emitter and detector. Ideal for sensing black-to-white transitions or can be used to detect nearby objects. IR Diode: This LED can handle up to 50mA of current and outputs in the 940-950nm IR spectrum. Use to send signal to talk to the included IR receiver diode or just turn off your neighbor's TV. 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.
