1.Introduction
The ACEBOTT QA003 MEGA 2560 R3 development board is a micro controller board based on the ATMEGA2560, featuring 54 digital input/output pins, suitable for designs requiring a large number of IO interfaces. Its processor core is the ATmega2560, with 54 digital input/output pins (of which 15 can be used as PWM outputs), 15 analog inputs, 4 UART interfaces, a 16MHz crystal oscillator, a USB port, a power socket, an ICSP header, and a reset button. It includes everything the micro controller needs, and you can easily drive it by simply connecting it to the computer’s USB port, using an AC-DC adapter, or using batteries. Compared to the UNO, it provides more IO ports, and its form and function are almost compatible with the UNO.
