- NEW IMPROVEMENT: Clearly print on the female header connector, more precise and easier to use the wire.
- 100% compatible with the official version and the software found on the Arduino website.
- Control using ATMEL ATMEGA328P chip
- 3.3VV/5V Supply Voltage and IO Voltage is optional. More 3.3V modules supported, such as Xbee module, Bluetooth module, RF module, GPRS module, GPS module, LCD5110 Backlight and so on, but the original version can only support 5V IO.
