Arduino Uno Compatible R3, Micro USB, 8 Analog Inputs

Arduino Uno Compatible R3, Micro USB, 8 Analog Inputs

New version of Uno R3

  • More analog pins. 8 total (A0-A7)
  • Micro USB cable


Compatible with Arduino Uno R3 board.


This is an Arduino Uno R3 compatible board. All features are exactly the same except for the USB chipset which uses a CH340 USB controller.

  • MCU: ATMega328
  • Operating Voltage: 5V
  • Digital I/O: 14 Digital I/O (of which 6 provide PWM)
  • Analog I/O: 6 Analog Inputs
  • Comm Interfaces: UART,SPI, I2C


Built on the ATmega328 microcontroller and USB-UART interface chip CH340G.
Board for functionality similar to the Arduino Uno (ATmega328).

Uno R3 CH340G/ATmega328 - connects to the computer via microUSB cable (used for almost all Android smartphones).
You can supply power to board through a MicroUSB connector or DC power socket.
The voltage regulator (LDO) can deal with incoming voltage from 6V to 12V DC.
Output current for 5V - about 800mA, for 3.3V - about 180mA
