Feature:

This is an Arduino Mega2560 compatible board, with a 12 MHz Atmel ATMega2560 processor and a CH340G USB driver.

It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analogue inputs, 4 UARTs (hardware serial ports), 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. 

This board uses the CH340G USB to serial chip, and is fully supported by the Arduino IDE (although additional drivers are needed for the USB interface).

Specification: 

Input Voltage: Recommended 7-12V, Limit 6-20V

Digital Input/Outputs: 54 (15 PWM capable)

DC current per I/O pin: 40mA

Flash Memory: 256 Kb (8KB is used by the bootloader)

Note:

Drivers are required for the USB interface on Windows (linux and recent OSX systems should not require anything). 

The USB to serial chip used is a CH340G, a commonly used device. Drivers for this chip are freely available online. 

Ebay does not allow us to include links to documentation or drivers on our listings, but searching for "wch-ic CH340G USB driver" should lead to suitable drivers.  

Package Includes:

1 Pcs Arduino Mega2560 R3 Compatible Board (With USB)
