ARDUINO UNO R3 CH340G USB-serial – compatible with Arduino Uno R3 board. Built on the Atmel ATmega328/168 microcontroller and USB-UART interface chip CH340G.
New version of Uno R3 – More analog pins – add A6, A7.
Board functionality similar to the Arduino Uno (ATmega 328/168). It is designed for affordability, but the same stable ans tested performance, and uses the original chip Atmel ATmega328 (16 MHz).
The board uses the CH340G chip as UART-USB converter. Stable data exchange when you work in the frequency 12Mhz (need install drivers to computer).
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 accept 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 for most of your projects.
