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.

Projects

Project 1. Hyduino - Automated Hydroponics with DFRduino Mega2560

Introduction: Hydroponics is growing plants without the use of a traditional dirt medium by using a nutrient-rich water solution. This is especially great for those people that have limited areas in their backyard to grow in.

Project 2. Simple Arduino based Bioresonance Therapy device, RIFE Machine.

Introduction: The purpose of this project was to explain how to make such a device yourself with "professional" features whose complete cost does not exceed twenty-five dollars. This is how I want to capture the real value of such devices that are sold today on the Internet.
