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.
