Dear，Pls leave a massage to tell us what design (Color) do you want.thank you.

Description:The Mega 2560 is an update for the Arduino Mega， which it replaces.The board is a microcontroller board based on the ATmega2560-16AU .It has 54 digital input/output pins (of which 14 can be used as PWM outputs)， 16 analog inputs， 4 UARTs (hardware serial ports)， 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. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.Product Summary:CH340G replace the Atmega 8U2/16U2CH340G Driver Download link， please copy the link and paste in browser: http://www.5v.ru/ch340g.htmMicrocontroller:ATmega2560Clock Speed:16 MHzEEPROM:4 KBSRAM:8 KBFlash Memory:256 KB of which 8 KB used by bootloaderOperating Voltage:5VInput Voltage (recommended):7-12VAnalog Input Pins:16Digital I/O Pins:54 (of which 14 provide PWM output)DC Current for 3.3V Pin:50 mADC Current per I/O Pin:40 mAPackage Included:1 x ATmega2560-16AU CH340G BoardNOTE:As the effect varies from monitor to monitor， there is irrevocable slightly difference in colors between the color showed on your monitor and the real one， So if dear you can not accept this very little difference， be cautious before you making the orders.thanks for understanding.
