The Uno is a microcontroller board based on the CH340.It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 inputs, a 16 MHz ceramic resonator, 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. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the CH340 programmed as a USB-to-serial converter Revision2 of the Uno board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode.
