  • Hey I’m just scratching the surface of how deep this topic really is, I have read some articles and at this point I’m really confused, if I plug the USB cable in and search for 5v pads what will I found the vbus line which at the moment is the cc ? Or the d+ with the bc1.2 ? And how do I know what standard is it using at the moment ? Anyway from the wireless charger I only get 3 cables out 5v gnd and ID (keep in mind I have bought wireless chargers with the lightening plug because I wasn’t aware of such a complicated standard and they were cheaper anyway since now it doesn’t work I will bui proper USB c Qi chargers … ) So as I understood I should add a 5.1 k resistor in series with the cc because the charging board is expecting a pull down right?







  • Thanks is there a way to know if the voltage spikes are properly filtered out without a spectrum analyzer I only have a multimeter ( and It shows something around 5v )I also noticed the coils will randomly die, I have altrady bought 2 from china and now I’m wondering if it has something to do with me charging the headphones via USB c while the coil Is plugged in … I Will add photos of the circuit as soon as possibile thanks again for your help
