About this product

The official Level 1 board of the National Edge AI Hackathon, bundled for Indian classrooms. Two processors share the work: a Renesas microcontroller runs your sketches while an ESP32-S3 handles Wi-Fi and Bluetooth, and a 12x8 LED matrix built into the board gives you something to program before a single wire is connected. Fits every UNO shield your lab already owns.
