How can I customize qi wireless charger module

The qi wireless charger module boards ADC would measure a voltage applied to one of the analog pins, but if you try to measure the voltage you supply, this is "auto-referential." You need to use a function called analogReference to set the ADC to work with an INTERNAL voltage, regulated and taken from the microprocessor, that will always be 1.1V so that, when the battery inevitably starts to lower its voltage, the comparison value shall be stable. This causes a problem; if the 0-1023 range has a maximum of 1.1V and your battery is about 4V, you have to lower the input voltage. How? With a "voltage divider" (you can find many references if you want to understand it better). The V D is a short circuit with just two resistors (values can be calculated here - the higher, the better for power consumption!).

These plates are ferrite sheets. They are used to conduct the magnetic field to increase the energy transfer efficiency. As it conducts the magnetic field, it will also reduce the magnetic field behind the ferrite sheet, which is essential on the receiver side (less electromagnetic interference, minor eddy current losses, less heat). A broken sheet will decrease the positive effect of the ferrite sheet. This means the charger will lose efficiency. This could potentially lead to overheating of the charger. Depending on the implementation, it will catch fire or turn down the power level to prevent overheating, resulting in a longer charge time. I'd get it replaced if you want to use it for a prolonged time. If you use it without having it in sight, I will get it replaced.

If your car doesn't come with wireless charging already built-in, you need to install a wireless charging device inside your vehicle. There's a wide range of designs and specifications, from the standard flat pads to cradles, mounts, and even chargers designed to fit a cup holder.
