Keyestudio Mega 2560 R3 Development Board (Arduino-Compatible)
Keyestudio Mega 2560 R3 Development Board (Arduino-Compatible), Keyestudio Mega 2560 R3 Development Board Keyestudio Mega 2560 R3 is a microcontroller board based on the ATMEGA2560-16AU, fully compatible with ARDUINO MEGA 2560 REV3. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 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. It contains everything needed to support the microcontroller. With its bootloader, program can be downloaded directly with USB. Just simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega 2560 board is compatible with most shields designed for the Uno. The 2560 R3 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 programmed as a USB-to-serial converter. We recommend this board for 3D printers and robotics projects.
