ATmega2560 R3 CH340 Boards Compatible with Arduino MEGA 2560 IDE- Lot of 5 or 10

ATmega 2560 R3 ATMEGA 2560, CH340 Board    The ATMEGA 2560 R3 is a microcontroller board based on the ATmega2560. 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, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; 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 ATMEGA 2560 board is compatible with most shields designed for the previous models. The ATmega 2560 R3 is an update to the ATmega, which it replaces.    The ATMEGA 2560 is designed for projects that require more I/O lines, more sketch memory and more RAM. With 54 digital I/O pins, 16 analog inputs and a larger space for your sketch it is the recommended board for 3D printers and robotics projects. This gives your projects plenty of room and opportunities maintaining the simplicity and effectiveness of the platform.       Specs:   Microcontroller ATmega2560    Operating Voltage 5V    Input Voltage (recommended) 7-12V    Input Voltage (limit) 6-20V    Digital I/O Pins 54 (of which 15 provide PWM output)    Analog Input Pins 16    DC Current per I/O Pin 20 mA    DC Current for 3.3V Pin 50 mA    Flash Memory 256 KB of which 8 KB used by bootloader    SRAM 8 KB   EEPROM 4 KB    Clock Speed 16 MHz    LED_BUILTIN 13   Length 101.52 mm   Width 53.3 mm    Weight 37 g
