The mega control board, among the series of MCUs , is the most popular since it has numerous pins. However, a substantial of pins don’t meet the space demand of DIY design. To tackle this issue, we roll out the Keyestudio MEGA PRO development board. In fact, its use method is as same as the official mega board, in addition to the different volume.
Its processor core is ATMEGA2560-16AU. In the meantime, it has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 channel serial communication ports, a USB connection, 1 ICSP header, and a reset button. And all ports are extended by pins with the interval of 2.54mm. What’s more, you can burn the firmware for ATMEGA2560-16AU through the built-in ICSP port. Luckily, the firmware of this chip is burnt well before delivery, therefore, you don’t need to burn firmware.
The power can be supplied through USB cable, port 5V, GND(DC 5V), as well as Vin GND(DC 7-12V).
