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.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eProgram 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.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
