What should I do with an unused Vbat pin? - Developer Help
Webb28 juni 2024 · Some of these interface pins are available on the SODIMM connector as regular GPIOs (SODIMM pin 43, 45, 93, 95, 105, 107, 127, 131, 137, and 138). This means the pins remain powered in the “RTC Only” power mode by the VCC_BATT rail. Make sure there is no back feeding on this pin. Webb3 juli 2024 · I see this can be configured as Vbat, but using MCC I have it set to GPIO output.

The VBAT pin (aka VCC or 5V) will get power from a 5V regulator. The 3.3V pin (aka VDO or 3.3) will get power through a 3.3V regulator (which is powered from the 5V regulator) USB will always run through a schottky diode to prevent BAT_IN from giving … plaster crafts molds
