BPI-UNO32 with ESP32 design
The Banana Pi BPI-TriodeCar is a product designed for education on entry-level engineering. Supporting both the BBC Micro:bit and Web:bit(BPI:bit), the TrideCar can also be equipped with peripherals such as, buzzer, and ultrasonic sensor.
Key Features
- Two switchable modes: a comparator(LM393) or with Micro:bit/ Web:bit.
- Supports MakeCode, Webduino Blockly, and MicroPython programming.
- Provides soldering area for more peripherals extension.
- I2C Connector(3.3V) onboard.
- Screwholes for LEGO blocks extension.
- Line Tracking.
