Introduction #
The ACEBOTT QA003 MEGA 2560 R3 development board is a micro controller board based on the ATMEGA2560, featuring 54 digital input/output pins, suitable for designs requiring a large number of IO interfaces. Its processor core is the ATmega2560, with 54 digital input/output pins (of which 15 can be used as PWM outputs), 15 analog inputs, 4 UART interfaces, a 16MHz crystal oscillator, a USB port, a power socket, an ICSP header, and a reset button. It includes everything the micro controller needs, and you can easily drive it by simply connecting it to the computer’s USB port, using an AC-DC adapter, or using batteries. Compared to the UNO, it provides more IO ports, and its form and function are almost compatible with the UNO.

Sample Code #
Connect the board to the computer using a USB data cable: Select “Arduino AVR Boards” -> “Arduino Mega or Mega 2560” from the Tools > Board menu. Choose the appropriate Port. And upload it to the board using the Upload button.
Wiring Diagram #
Sample Code #
void setup() {
Serial.begin(9600);//The serial port baud rate is set to 9600
}
void loop() {
Serial.println("Hello,QA003 MEGA 2560 R3");
delay(1000);//Delay for 1 second.
}
Test Result #
After uploading the program, open the serial monitor in the Arduino IDE to observe the continuous serial printing of “Hello,ACEBOTT QA003 MEGA 2560 R3”.
