Arduino Compatible Funduino Mega 2560 R3

Description

The Funduino Mega 2560 R3 is fully compatible with Arduino Mega 2560. The Funduino brand is marked on the board to distinguish it with the official Arduino products. It is 100% compatible with Arduino Uno software.

The Mega 2560 has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analogue inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.

The Mega 2560 differs from the preceding Mega in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter. This auxiliary microcontroller has its own USB bootloader, which allows advanced users to reprogram it

It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.
