A QVGA camera module with ultra-low power consumption, configurable 1-bit video data serial interface with video frame and line sync, and the monochrome sensor makes image processing an easy part for most machine vision applications.
The small TFT display at the back of Pico4ML is a 160×80 LCD, it’s connected to the board through the SPI interface, you can do a live preview of the camera, or display the results of any of the your ML models in real-time.
The audio chip on the Pico4ML is capable of directly outputting PDM (Pulse-density modulation) signals, this integration allows the RP2040 to receive audio input, and it’s great for all the speech/voice recognition models. Motion tracking is also a built-in feature, the 2.5 mW low-power 9-axis IMU we used is just another ideal match for the RP2040 chip.
Arducam Pico4ML is completely open-source, all its codes, design files, and schematics will be made available for anyone to use, rebuild or modify.
Microphone on board
“Hey, Google” “Alexa.” Use a pre-trained speech detection model to provide always-on wake-word detection using a tiny microcontroller.
IMU on board
Wave it to cast several types of spells in one of the following three gestures: “Wing”, “Ring” and “Slope”.
Camera Module on board
Classify Images captured by a camera to recognize if a person is in the camera input or not
