Atmega328p Ch340g Smd Wifi Development Board 3 Ch340 Atmega328 with Cable For UnoR3

This is new improved version.The main features are:
1. Replace IC ATmega328P-PU with QFP package to be Atmega328P-AU while keeping the microprocessor controller unchanged,
2. Replace the USB chip to solve the traditional UNO board in Win7 and Win8 system above the incompatible unstable situation,
3. The USB interface is replaced with micro interface, so all mobile phone charging cable can be downloaded easily and cost can be saved.
4.Add plug pin for convenience to friends who like pin arrangement.
