Uno R3 Board based on Arduino:
This is the updated Uno R3 board, which inherits all the features of its predecessor while replacing the 8U2 with an ATmega16U2 (previously 8U2 or FTDI on earlier models). This change results in faster data transfer rates and expanded memory capacity. No drivers are required for Linux or Mac operating systems, and this Uno board can also emulate various USB devices like keyboards, mice, and joysticks.
