Change the in-line package of ATmega328P to flat package

CH340G Chip replaces ATmega16U2 chip.

The driver will be automatically installed when Plug the R3 controller board. Select the board, R3 inside the IDE. Select the COM port, this can be queried in My Computer, just inside your R3 port development board.
UPGRADED R3 - The CH340 development board is equipped with new version R3 and compatible with Arduino and its software. The components and materials are eco-friendly.
UNIQUE FEATURE - The development board features straight pin header 2.54mm, with main chip ATmega328P, CH340G functioning well inside and pin sockets for better use of DuPont wire. (CH340 driver is NOT included but available on request)
ENHANCED PERFORMANCE - The IDE development kit microcontroller comes with 2 sets per package with USB cables included and perfectly troubleshoots the problems resulted from instability and incompatibility of the traditional R3 for Windows 7 and Windows 8 systems.
STRONG COMPATIBILITY - The developer board supports both 3.3V and 5V power supply and can meet different IO expansion requirements including temperature humidity sensor, Xbee module, BT Bluetooth module, RF module, GPRS module, GPS module, LCD shield and more.
