Compatibility
This board is fully compatible with the Arduino IDE and works seamlessly on Windows, macOS, and Linux. It uses the ATmega32U4's native USB interface, so no external programmer is needed. For external circuits, pair it with 5V sensors and modules typical in Arduino ecosystems.
Wiring Notes
Header pins are pre-soldered, but exercise care when handling the compact board to avoid shorts. Power can be supplied via the micro USB port or the Vin pin (7–12V recommended). Always ensure I/O pin voltages do not exceed 5V to prevent damage.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno shields?
The Micro's pinout differs from the Uno, so standard shields are not directly compatible without an adapter or custom wiring.
Can I use this as a USB keyboard or mouse?
Yes, the ATmega32U4 supports native USB HID, so you can easily program it to emulate keyboard strokes or mouse movements.
Does it include a built-in programmer?
The Micro does not require an external programmer; it appears as a USB device and can be programmed directly from the Arduino IDE via its bootloader.
