Powering the KV4P module #92

Closed mikey69bg closed 4 days ago

mikey69bg commented 1 week ago

Hello, my question is, is it possible to implement a separate power supply for the module - not to use the smartphone battery, but to add a battery mounted inside the module? For example, two 18650 Li-Po cells connected in series, and after them there should be a voltage regulator to provide +5V for the ESP32 and the radio module.

@mikey69bg you can use a USB C adapter like this that includes a power-in port (select "Color: C female-C-C"):

I've tested this, and can power both my phone and the kv4p HT with an external battery bank. If this isn't what you meant, please feel free to reopen this issue with more details about what you'd like it to do.

Thanks!
