MC-MEGA is a microcontroller board based on the ATmega1280 (datasheet). 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 an AC-to-DC adapter or battery to get started.
The MC‑MEGA is an Arduino™ compatible development board based on the ATmega1280 microcontroller. It offers 54 digital I/O pins (14 PWM), 16 analog inputs, four hardware UARTs, a 16 MHz crystal, USB connectivity and a power jack.
The handbook covers power supply options, pin assignments, communication interfaces, programming methods, automatic reset behavior, USB over‑current protection, mechanical dimensions and reference design files.
