Arducam Pico4ML TinyML Dev Kit - development kit with RP2040 microcontroller and Bluetooth 5.0

Description

Development kit with the RP2040 microcontroller, which is equipped with two ARM Cortex-M0 + cores operating at 133 MHz and 264 kB RAM. The board also has a QVGA camera with a resolution of 320 x 240 at 60 fps, an LCD display, an IMU chip and a microphone, and wireless communication is provided by a Bluetooth 5.0 module.

The board's equipment makes the set a perfect test platform for projects using artificial neural networks to process sounds, images or motion. The platform supports the popular MicroPython and C / C ++ programming languages. Programs can be uploaded to memory via the USB interface in mass storage mode.
