UNO R3 is a microcontroller board based on the A-T-mega328P. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, 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.

1.Add two rows of the holes for the pins. So it can be connected with normal Dubond line.
2.Add 3 rows of the holes for wiring.
3.Change the in-line package of A-T-MEGA328P to flat package.
4.CH340G Replace A-T-mega16U2.
5.Plug UNO development board, the driver will be automatically installed.
