Arduino Uno R3 ATMEGA16U2 Clone

This board is an Uno R3 compatible version of the latest iteration of the Arduino Uno which is the most popular of the many development boards available for hobbyists.

• Uno R3 with ATmega16U2 USB-C

• ATmega328 processor running at 16MH
• Atmega16U2 programmed as serial to USB converter
• 32KB Flash memory
• 14 Digital I/O
• 6 PWM shared with the digital I/O
• 6 Analog inputs that can also be used as digital I/O for a total of up to 20 digital I/O
• 1 Hardware serial port
• 5V Operation with USB C connector

The Uno R3 operates at 5V which can be supplied via an external power supply or through the USB-C connection.  The power source is selected automatically if both are available.  If an external supply is used, it is recommended to use a supply between 7-12V.  Higher input voltages will cause the on-board regulator to work harder and may cause it to overheat.
