Arduino UNO R4 Minima User Manual

Arduino® UNO R4 Minima
10 / 17 Arduino® UNO R4 Minima Modified: 19/06/2023
8.2 Pin Voltage
The UNO R4 Minima operates on 5 V, as does all pins on this board except for the 3.3V pin. This pin draws power from
the VCC_USB pin on the R7FA4M1AB3CFM#AA0, and is not connected to the buck converter.
8.3 Pin Current
The GPIOs on the R7FA4M1AB3CFM#AA0 microcontroller can handle up to 8 mA. Never connect devices that draw
higher current directly to a GPIO.
In case you need to power external devices that require more power, e.g. servo motors, use an external power supply.
