DFRobot UNO R3 Arduino compatible board

DFRduino Uno V3.0 from DFRobot is a compatible Arduino board ideal for schools or hobbyists. It serves as a good entry-level microcontroller board that is fully compatible with Arduino UNO R3 and the open-source development environment Arduino IDE. This board features the ATmega16U2 as a USB-to-serial converter. An additional advantage is that the DFRduino UNO R3 board uses the AVR chip in the DIP package, allowing easy removal of the chip for firmware updates or reprogramming, or for use in a more compact project.

The headers have different colors to indicate various types of I/O ports, matching DFRobot's sensor cables. This color coding simplifies the process of connecting sensors, helping to identify which side is analog (blue) or digital (green). The Arduino Uno is based on the ATmega328 microcontroller, featuring 14 digital input/output pins (six of which can be used as PWM outputs), six analog inputs, a 16 MHz crystal oscillator, a USB port, a power supply socket, an ICSP header, and a reset button. It contains everything needed to support the microcontroller.
