How to connect external power through the BQ24040 battery charger IC on the Expansion Board 2.1



  • The spec sheet for the Expansion Board 2 says it uses a TI BQ24040 battery charger IC. That IC's spec sheet says it can take inputs up to 6.5 VDC before over-voltage protection kicks in.

    I've got a solar panel (with varying voltage) and want to use it to power the device through the BQ24040. Is the power input on the USB connector a (the) way to do this?
