How to develop a USB Host device with the Xiao ESP32-S3

[cgwaltney]

what are you trying to use the extra USB port for… we assumed communicating with another device/computer

you would not be able to use this extra USB to charge anything

How can I charge the battery faster than 150 mA on the Xiao RA4M1?

Basically it’s the same as the XIAO charging design. VBus turns off the VBat. [XIAO_PowerSwitch] Edit> Since the BQ25180 has an integrated mosfet to isolate the battery from the SYS voltage, your approach should work fine, ie SYS voltage into the VBat on the XIAO base via a reverse biased diode (to prevent the XIAO’s charger from disrupting your charger - although I’d do some tests on whether that is an issue or not).
