      I want to power [this board](https://www.waveshare.com/wiki/RP2040-Touch-LCD-1.28) with a 14v battery. The board has a 1s battery connector that can power the board and read the voltage via ADC. Is there something I could place between the two to lower the voltage and still have a battery voltage reading? I would not be charging the battery through this. The usb port would not be open in the final product.\n

      My understanding is that voltage splitting with resistors is not recommended for powering. And a buck converter will only give constant voltage reading.
