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.
