The Arduino Uno R3 CH340G USB-serial is compatible with the Arduino Uno R3 board. This Arduino Uno is built on the Atmel ATmega328/168 microcontroller and USB-UART interface chip CH340G. This is the new version of Uno R3 with more analog pins and additional A6, A7. The board's functionality is similar to the Arduino Uno (ATmega 328/168). It is designed for affordability, but the same stable and tested performance, and uses the original chip Atmel ATmega328 (16 MHz). The board uses the CH340G chip as a 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).
