Only when USB-C is connected, VBUS has voltage When only the battery is connected, VBUS has no voltage output If you want to connect an external power supply without connecting USB-C, VBUS Pin is the only voltage input pin. Please note that the maximum input of VBUS Pin is 5V, do not exceed 5V Can other GPS antennas be used? The external GPS antenna must be an active GPS antenna with a 3.3V power supply. For example, the MK-76 supports 2.5 - 5.5V and is compatible. Most active GPS antennas support 2.5 - 5.5V power.
