Arduino Compatible Mega 2560 Microcontroller
Vetco stocks 100% compatible equivalents to the very popular Arduino series of Microcontrollers. The Arduino is the easist way to get started in the world of microcontrollers and it has an extremely active hobbiest community. The programming software is free and there are many, many toutorials and code samples available for FREE online.

The Arduino Compatible Mega 2560 is a microcontroller board based on the ATmega2560. This is the bigger brother to the Arduino compatible UNO microcontroller that we sell, with more memory and more I/O pins. 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. This Mega is compatible with most shields designed for the Duemilanove or Diecimila.

  • Microcontroller: ATmega2560
  • Operating Voltage: 5VDC
  • Input Voltage (recommended): 7-12VDC
  • Input Voltage (min/max): 6-20VDC
  • Digital I/O Pins: 54 (of which 14 provide PWM output)
  • Analog Input Pins: 16
  • DC Current per I/O Pin: 40mA
  • DC Current for 3.3V Pin: 50mA
  • Flash Memory: 256KB* (*8 KB used by Arduino bootloader)
  • SRAM: 8KB
  • Clock Speed: 16MHz
  • USB-C Connection

This item is just the Arduino compatible Mega 2650 Microcontroller. No additional shields, power supplies, cables, software or other accessories are included. This board is 100% compatible with the official Arduino branded boards and is supported directly by Vetco Electronics for warranty purposes. Vetco sells an ever increasing selection of Arduino shields and Arduino sensors.


DRIVER AND INSTALLATION NOTICE: Please use this driver to install the USB to Serial on the Uno, Uno With Removable Chip and MEGA: located above under the "Additional Files" section.

There are any one of THREE types of USB to Serial chips included with Arduinos now days. You could have a Standard Uno chip which the IDE has the driver for. You could have a CH341 Chip, which you MUST download the "DOWNLOAD ch341ser DRIVER" to use. OR you may have the FTDI chip which you MUST download the "FTDI_Arduino_Driver_CDM21228_Setup" driver to use.

Vetco does not support the use of discontinued operating systems like Win 98, Win XP, Win Vista, Win 7 or Win 8/8.1. Though you may be able to get these drivers and boards to work on these older systems, we can not supply support or assistance.

These drivers (even the one marked MAC) are not compatable with M1, M2 or M3 Macs. They are for Intel Macs Only! Vetco does not have access to an M1 or M2 Mac and can not assist with any attempt to get these working with M1/M2 Macs.

We do offer limited assistance if you are using a laptop and can bring it into our store. We will upload a guide for installing Arduino drivers.
