DFR0323

DFR0323 is a Bluno Mega2560 controller board. It inherits the advantages of Bluetooth 4.0 wireless communication function, also enables more digital and analogue ports allowing bigger code storage space. Users can use Bluno Mega2560 to make more functional DIY works. Also improvement has been done on power supply, with the power input range widened to 5-23V. Arduino Mega is the high-end series of the Arduino controller. DFRduino Mega2560 is based on ATmega2560 control chip as the core, with 54 digital I/O (input/output) ports (of which 14 can be used as PWM output), 16 analogue input ports and 4 UART (hardware serial ports), using a 16MHz crystal oscillator. Embedded bootloader enables the controller to download the program directly via USB without any other external burning device. Multiple ways of power supply can be free to choose, including the USB power supply and universal power adapter and battery for external power supply.
