Arduino Mega 2560: Pins for everything

When 54 digital I/O and 256 KB of flash are not too much.

Arduino Mega 2560: Pins for everything

01Specs that matter

  • 54 digital I/O (15 PWM).
  • 16 analog inputs.
  • 256 KB flash, 8 KB SRAM.
  • 4 hardware serial ports.

02When to use Mega

Choose Mega when a project needs many sensors, several displays, multiple motors, or a 3D printer firmware like Marlin.

03Limitations

Still 5V/16 MHz — for heavy math or AI use ESP32-S3 or Teensy instead.
