DFRduino UNO R3

SKU: DFR0216

The DFRduino UNO R3 is a compact microcontroller board compatible with Arduino IDE and open-source development environments. It features an ATmega16U2 for USB-to-serial conversion and a DIP package AVR Chip for reprogramming flexibility. The board includes color-coded headers for easy identification of power, analog, and digital I/O ports, aligning with sensor cables for straightforward connectivity. With SDA, SCL, and IOREF pins, it's prepared for future compatibility with voltage-adaptive shields. This versatile board supports 14 digital I/O pins (6 PWM outputs), 6 analog inputs, and is powered easily via USB or an AC-to-DC adapter.
