Introduction
This is DFRduino UNO. It is compatible with Arduino UNO. However, we uses FT232 instead of 8u2. The difference between UNO and dumelinove is the downloading speed which is almost two times faster.
The Arduino UNO is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
