Introduction
The new version of DFRduino Mega2560 has improved the VIN power supply circuit by changing the easily overheat LDO to DC-DC circuit for ensuring safety and reliability in long-term use. In addition to optimizing the overheating issue, it offers a wider input voltage range. What’s more, DFRduino Mega2560 can work steadily even when only powered by a 3.7V lithium battery.
DFRduino Mega2560 is an ATmega2560-based microcontroller that provides full compatibility with "Arduino MEGA2560“. It features 54 digital I/O ports, 16 analog signal input ports, 4 UARTs(hardware serial ports), and a 16MHz crystal oscillator. The board comes with a bootloader that enables users to download programs directly via a USB. You can simply power it with a USB cable or a standard adapter or use a battery as external power. Mega 2560 has 256KB FLASH, two times of Mega1280, which could offer a larger create space for your projects.
