The Pico4ML comes without header pins; the 40-way male straight header pin is available here. This is a small development board built on the powerful Raspberry Pi RP2040 dual-core ARM Cortex M0+ microcontroller CPU. Pico4ML includes the RP2040 as the primary controller, a QVGA camera as an image sensor, an Inertia Measurement Unit (IMU), a 0.96″ graphic display as the output for displaying messages, and a microphone for voice input. It is a sturdy tiny TFLite Micro board designed just for running and training machine learning instances.
