Keyestudio Mega 2560 R3 is a powerful microcontroller board built around the ATMEGA2560-16AU, offering full compatibility with the Arduino MEGA 2560 REV3. It boasts 54 digital input/output pins, with 15 supporting PWM output, alongside 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, 2 ICSP headers, and a reset button.
Designed to provide all the essentials for microcontroller operation, the board includes a bootloader that allows programming directly via USB, eliminating the need for an external programmer. Simply connect it to a computer using a USB cable or power it with an AC-to-DC adapter or battery to begin.
Compatible with most shields built for the Uno, the Mega 2560 R3 stands apart from its predecessors by replacing the FTDI USB-to-serial driver chip with the Atmega16U2, programmed as a USB-to-serial converter.
Tailored for advanced projects, the MEGA 2560 offers extensive connectivity options, generous memory, and a versatile design—making it the preferred choice for 3D printing, robotics, and other complex applications. With ample space for coding and expansion, it opens up new possibilities for innovative projects.
