Adafruit TensorFlow Lite for Microcontrollers Kit
Adafruit TensorFlow Lite for Microcontrollers Kit allows developers to start with TensorFlow models and machine learning. The kit uses the PyBadge as the edge processor that can run CircuitPython, MakeCode Arcade, or Arduino. The ATSAMD51 powers this compact credit-card-sized board with 512KB of Flash, 192KB of RAM, and 2MB of QSPI flash for file storage, handy for TensorFlow Lite files, images, fonts, sounds, or other assets. Plug in a microphone for micro speech recognition. Adafruit's Arduino library offers demos to get started with and to recognize various word pairs like "yes/no," "up/down," and "cat/dog."
