Overview Iteaduino MEGA2560 is a derivative version of the Arduino MEGA 2560. It’s designed is basing on Arduino MEGA 100% compatible to its existing program and Arduino shields but the smaller size lower power consumption and with much practical improvement. In addition it has all ATMega2560 pins breakout which more 16 pins than Arduino MEGA 2560. Note: It does not support all the Mega shields because of the size. Basic features Arduino shields compatible 3.3V / 5V operation level Wide range power supply and low power consumtion Small size but all ATMega2560 pins breakout Hardware Pin Map Pin of Arduino Pin of Atmega Pin of Arduino Pin of Atmega D0 PE0 RX2 PH1 D1 PE1 TX2 PH0 D2 PE4 D18 PD3 D3 PE3 D19 PD2 D4 PG5 D22 PA0 D5 PE3 D23 PA1 D6 PH3 D24 PA2 D7 PH4 D25 PA3 D8 PH5 D26 PA4 D9 PH6 D27 PA5 D10 PB4 SS PB0 D11 PB5 MO PB2 D12 PB6 MI PB3 D13 PB7 SCK PB1 A0 PF0 A6 PF6 A1 PF1 A7 PF7 A2 PF2 A8 PK0 A3 PF3 A9 PK1 A4 PF4 SDA PD1 A5 PF5 SCL PD0 Microcontroller ATMega2560 Max Frequency ATMega2560 RAM Capacity 8K FLASH Capacity 256K External Resources No Power Supply External 12V External 24V External 7V External 9V USB 5V I/O Operation Level 3.3V 5V
