This carrier board combines a 2.4' TFT display, six addressable LEDs, onboard voltage regulator, a 6-pin IO connector, and microSD slot with the M.2 pin connector slot so that it can be used with compatible processor boards in our MicroMod ecosystem. We've also populated this carrier board with Atmel's ATtiny84 with 8kb of programmable flash. This little guy is preprogrammed to communicate with the processor over I²C to read button presses.

It's like a thermal camera, only at a lower resolution. To make it even easier to get your low-resolution infrared image, all communication is exclusively through I²C, using our convenient Qwiic system. However, we still have 0.1"-spaced pins if you prefer using a breadboard.
The AMG8833 Grid-EYE from Panasonic has an accuracy of ±2.5°C with a temperature range from 0°C to 80°C. Moreover, this IR 'camera' board can detect human body heat at about 7 meters or less and has a frame rate of 10 frames per second to one frame per second. It is important to point out that, although this version of the Grid-EYE is the most powerful type with high gain, it only tolerates 3.3 V.

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.
Onboard each moto:bit are multiple I/O pins, as well as a vertical Qwiic connector, capable of hooking up servos, sensors and other circuits. At the flip of the switch, you can get your micro:bit moving! The moto:bit connects to the micro:bit via an updated SMD, edge connector at the top of the board, making setup easy. This creates a handy way to swap out micro:bits for programming while still providing reliable connections to all of the different pins on the micro:bit. We have also included a basic barrel jack on the moto:bit that is capable of providing power to anything you connect to the carrier board.

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 °C ~ 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.
