Programming Interface: USB (no external programmer required)

Applications

Custom keyboards and keypads
Game controllers
Wearable electronics
Compact embedded systems
MIDI controllers

Notes

The Pro Micro does not have a built-in voltage regulator on the RAW pin, so ensure the input voltage matches the board's operating voltage.

Be cautious when connecting external components, as the Pro Micro is more sensitive to overvoltage and incorrect wiring compared to larger Arduino boards.
