Arducam Pico4ML – RP2040 TinyML Dev Kit

This Arducam Pico4ML dev board has been made exclusively for running and training machine learning examples. It is powered by the RP2040 microcontroller, and has a HiMax HM01B0 camera module with up to a 320 x 240 resolution for real-time image capture.

It comes with an ICM-20948 for gesture and motion detection, and a mono-channel microphone for audio input with direct PCM output. The board has a 0.96′ LCD SPI display (160 x 80) that is connected to the board through the SPI interface, you can do a live preview of the camera, or display the results of any of your ML models in real-time, making it an excellent choice for compact machine vision and TinyML projects.
