To power the UNO R4 Minima you may either use a USB-C® cable or the VIN pin.

If you’re using the USB-C® connector you must power it with 5 V.
The board can be powered via the VIN pin, supporting a range between 6-24 V. The VIN pin is also connected to the DC-jack (barrel plug connector).

When powered via the VIN pin, you are using the onboard regulator to bring down the voltage to 5V, which means that the 5 V pin can provide up to 1.2 A. Keep in mind that this voltage regulator also powers the rest of the circuit board, including the MCU, LEDs among other components.

***External devices with a high current draw (e.g. servo motors) should never be powered via the 5 V pin. It is mainly intended for devices drawing lower current such as sensor modules.***

If you’re using the USB-C® connector you must power it with 5 V.

When powered via USB, you are bypassing the onboard voltage regulator completely. In this case, the 5 V pin can provide up to 2 A without damaging the board.

The board can be powered via the VIN pin, supporting a range between 6-24 V.
