Compatibility
This board is fully compatible with the Arduino IDE and code written for the Arduino Leonardo, leveraging the same ATmega32U4 and native USB. It operates at 5V logic, so connect only 5V‑tolerant components. While designed for a compact footprint, standard shields can be used with a breakout adapter.
Wiring Notes
Program and power the board via the micro‑USB connector. The onboard regulator accepts 7–12V on the VIN pin; the 5V pin provides regulated 5V output. Note the 3.3V pin supplies up to 50 mA only, so use an external regulator for higher‑current 3.3V peripherals.
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 Leonardo?
Yes, it uses the identical ATmega32U4 microcontroller and is programmed the same way. Sketches written for the Leonardo run without modification.
Does it come with headers soldered?
Yes, this version includes male header pins pre‑soldered, so you can plug it straight into a breadboard.
Can I use it as a USB HID device?
Absolutely. The ATmega32U4’s native USB support lets you emulate a keyboard, mouse, or game controller without extra drivers.
