Product Description

UNO R3 MEGA328P ATMEGA 16U2 for Arduino



Quick Detail:
Funduino UNO R3 launched an easy way to use open-source controller hardware and UNO and no major changes.The biggest difference is that the USB to serial part of the circuit switch is a ATMega16U2 microcontroller.But the software part is the same as before.

Description:
Pin changes plus two I2C pins (SDA and SCL: next to the AREF pin, the Analog 4 and 5 copy, not the additional I2C interface), added two pins, theRESET next one is IOREF, , allowing the expansion board to adapt to on-board voltage, this pin is just told to expand the board's current on-boardvoltage (for example,UNO is 5V, the power supply pin can be seen as copy, does not provide the level pull-up), and the other is after inactiveplaceholder pins.
