New version of Uno R3 - More analog pins. Add A6, A7.

Uno R3 CH340G/ATmega328 - compatible with Arduino Uno R3 board. Built on the Atmel ATmega328 microcontroller and USB-UART interface chip CH340G.
Board for functionality similar to the Arduino Uno (ATmega328). It is a budget, but the same stable, and uses the original chips Atmel ATmega328 (16 MHz).
The board used the chip CH340G as converter UART-USB. Chip CH340G - is a budget solution. When you work in the frequency 12Mhz, giving a stable result of data exchange (need install drivers to computer).
Uno R3 CH340G/ATmega328 - connects to the computer via microUSB cable (used for almost all Android smartphones).

You can supply power to board through the MicroUSB connector or DC-jack. 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

(Please note that the higher the input voltage the lower the outgoing current). That will provide a reliable power most of your initial projects.

Specification :

  • Microcontroller - ATmega328, SMD execution ,
  • USB-UART interface - CH340G,
  • Input voltage of 6-12V,
  • MicroSUB - socket connection ,
  • DC-jack ,
  • 14 digital inputs / outputs (6 outputs PWM )
  • 8 analog inputs ,
  • 32k flash - memory ,
  • 16 MHz clock frequency ,
  • EEPROM: 1 KB ,
  • Constant current for each pin of the microcontroller 40 mA .
