There is no 5V pin available on the Nano ESP32. 5 V can only be provided via the **VUSB**, which is supplied directly from the USB-C® power source.
There is no 5V pin available on the Nano ESP32. 5 V can only be provided via the **VBUS**, which is supplied directly from the USB-C® power source.

While powering the board via the VIN pin, the VUSB pin is not activated. This means you have no option of providing 5 V from the board unless powered via USB or externally.

**Note:** This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.

### 5V Pin / VUSB
### 5V Pin / VBUS

The Nano ESP32 is the first board to not feature a **5V** pin. It has instead been replaced with VBUS, which is a more accurate description of the pin's capabilities.
