I/O pins, 16 analog inputs and a larger space for your sketches Ideal for: 3D printing, CNC robotics Compatible with most shields designed for the Arduino Uno. Because the Mega is the biggest Arduino microcontroller, this beast has the highest number of pins and is therefore suitable for large projects where a lot of devices have to be connected to the microcontroller. ![]() Development Boards & Kits - AVR Arduino Mega 2560 Rev3. EDITED TO WORK ON THE ARDUINO MEGA #if defined(_AVR_ATmega328P_) & defined(ILI9488_KBV_H_) //#define USE_SERIAL_COMPLEX //optimised C code for Uno, Xmega. Due to the many numbers of pins, it is not usually used for common projects but you can find them in much more complex ones like Radon detectors, 3D printers, temperature sensing, IOT applications, real-time data monitoring applications etc. 8-bit Microcontrollers - MCU 256kB Flash 4kB EEPROM 86 I/O Pins.
