## Description

Ideal for rapid prototyping and automation projects, the board offers ATmega328 at 16MHz with removable microcontroller, stable USB connection via reprogrammable ATmega16U2, 14 digital pins including 6 PWM and 6 analog inputs, power supply via USB or 2.1 x 5.5mm jack with AMS1117 5V regulator, includes ICSP and Reset button.
Arduino compatible development board, UNO R3 ATmega16U2. The development board is based on the ATmega328 microcontroller and offers 16 digital pins usable as Input or Output, of which 6 can be used as PWM and 6 Analog Input pins. It uses a 16MHz crystal, a USB type B connector, it is provided with a 2.1 x 5.5mm power plug on which the board can be powered with a voltage of 9V thanks to the integrated 5V AMS1117, ICSP and a Reset button.
The board differs from other models in that the microcontroller is removable and by using an ATmega16U2 programmed as a USB to Serial controller (the auxiliary microcontroller has its own bootloader that can be reprogrammed).
