Description
When a project needs more pins, more memory or more serial ports than an UNO can give, the Mega 2560 is the next step. It runs the same Arduino code and accepts most UNO shields, but has 256 KB of flash and 54 digital pins – the reason it powers most RAMPS 3D printers and multi-sensor robots.
Features
- ATmega2560 at 16 MHz: 256 KB flash, 8 KB SRAM, 4 KB EEPROM
- 54 digital I/O (15 PWM) and 16 analog inputs
- 4 hardware UARTs – run GPS, Bluetooth and a display on separate serial ports
- CH340G USB-to-serial, USB Type-B socket
- Power from USB or a 7–12 V DC barrel jack
Getting started
Select Arduino Mega or Mega 2560 in the Arduino IDE. Install the CH340 driver if the COM port doesn't appear.
Package includes
1 × Mega 2560 R3 compatible board, 1 × USB A-to-B cable
