Note: DFRduino Mega1280 is discontinued now, we recommend DFRduino Mega2560 as a suitable replacement.
DFRduino Mega1280 is a microcontroller board based on the ATmega1280. It has 54 digital input/output pins, 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. Because it has bootloader, it can download programs directly from USB. There is no need to use other external programs to burn.
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. The 128KB FLASH space allows it to completely replace the Arduino MEGA2560 in some of its intermediate and lightweight applications. Anyway, this is a cost-effective controller.

| Features |
*Designed for domestic Arduino fans. Full compatible with Arduino UNO R3.
*Suitable for Arduino Beginners.
|
*Low-cost main controller board. The main difference from the official one is that this board offers XBee socket and SPI directly-plugged interface, making the best of UART ports.
*For the low-cost project, and Arduino communication module development.
|
*DFRduino Mega 2560 comes with plenty of IO ports, 54 digital ports, 16 analog ports, and 4 UARTs.
*Applicable to large projects that require many sensors.
|
*Mega1280 has as many IO ports as Mega256, but comes with a smaller Flash. Besides, its price is lower than Mega2560.
*Suitable for low-cost projects requiring many sensors.
|
*Romeo V1 is specially designed for robot fans. It integrates motor driver, all sorts of communication ports, IO expansion port, and so on.
*Extremely suitable for robot fans.
|
*The only difference between V1 and V2 is that Romeo V2 adopts ATmega32u4 chip, which provides 2 UARTs, convenient for wireless communication.
*For robot fans to build up projects with wireless communication.
|
*The first Arduino compatible controller board that integrates Bluetooth 4.0, bring much more flexibility and the possibility for Android and IOS mobile development.
*For Android and IOS mobile App BLE developers.
|
*Integrated CC3000 wifi core and SD card function. Can store a large number of collected data. Compared with the Wifi shield, wido is more lightweight and low-cost.
*For IoT developers.
