MEGA 2560 R3 Board with USB Cable

The Mega is 100% compatible with Arduino IDE and most of the shields are designed for the Arduino mega2560 R3，RoHS Compliant The chip is Atmega2560-16au and Atmega16u2, same with the official version. Improved and expert version: 1. 0 pinout: added SDA and SCL pins that are near to the AREF pin Stronger RESET circuit. Use 5. 5 * 2. 1mm DC barrel jack (compatible with 5. 5 * 2. 5mm DC barrel jack) It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. Elegoo Mega 2560 R3 Elegoo Mega 2560 R3 is an AT mega2560 micro-controller board. It is designed for more complex projects. It would be an intelligent choice of board for 3D printers, robotics projects and more other projects with 54 digital I/O pins (of which 15 can be used as PWM outputs), 16 analog inputs and a larger space for your sketch. This gives your projects plenty of room and opportunities. Product Details Extra Points: Besides the 54 digital I/O pins and 16 analog inputs, it also has 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It provides everything needed to support the micro-controller. You will simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. Simplification and Security: The ATmega2560 on the Elegoo Mega 2560 comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. The Mega 2560 has a re-settable fuse that protects your computer's USB ports from shorts and over-current. Although most computers provide their own internal protection, the fuse provides an extra layer of protection . If more than 500 MA is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed. Memory Store: The ATmega2560 of Elegoo Mega 2560 R3 Controller Board has 256 KB of flash memory for storing code (of which 8 KB is used for the bootloader), 8 KB of Spram and 4 KB of EEPROM (which can be read and written with the Eeprom library). Diverse Power Methods: The Elegoo Mega 2560 R3 can be powered via the USB connection or with an external power supply. The power source is selected automatically. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. Leads from a battery can be inserted in the GND and Vin pin headers of the POWER connector.
