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
