Have 54 digital input/output pins (of which 15 can be used as PWM outputs). RX responds to D0（digital port), TX responds to D1（digital port) Used to set the external reference voltage(0-5V)Ĭan be connected to press button, as same as reset button The power can be supplied through USB cable, port 5V, GND(DC 5V), as well as Vin GND(DC 7-12V). Luckily, the firmware of this chip is burnt well before delivery, therefore, you don’t need to burn firmware. What’s more, you can burn the firmware for ATMEGA2560-16AU through the built-in ICSP port.
And all ports are extended by pins with the interval of 2.54mm. 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.
In fact, its use method is as same as the official mega board, in addition to the different volume. To tackle this issue, we roll out the Keyestudio MEGA 2560 PRO development board. However, a substantial of pins don’t meet the space demand of DIY design. The mega 2560 control board, among the series of MCUs, is the most popular since it has numerous pins.
