Introduce
Mega2560-CORE is a small, complete and breadboard-friendly board base on the ATMega2560。Its design is based on the Arduino Mega2560，so we can use it as a Arduino Mega2560 development board. In a different place, it lacks only a 6-foot download port and a reset switch. Reducing the hardware circuit that can we reduce the power consumption and the cost. Mega2560-CORE has a matching download line and the other one end of the download cable is a USB interface, so it is very convenient for use.
Features
● Microcontroller ATmega2560
● Operating Voltage (logic level) 3.3V or 5 V
● Digital I/O Pins 54 (of which 15 provide PWM output)
● Analog Input Pins 16
● DC Current per I/O Pin 40 mA
● Flash Memory 256KB
● SRAM 8 KB
● EEPROM 4KB (ATmega2560)
● Clock Speed 16 MHz
● Low power consumption, low cost
