I've updated the PCB with slightly different design, but most importantly with USB Type-C connector!🤓
So you told me the two "holes" near the USB port are like a backup power supply. Can you guide me on how to use that?
You have two holes on the PCB, the square one is +5V input and it has a '+' sign next to it, the other round one is GND 😄 You can use a microUSB adapter PCB or an USB Type-C adapter PCB to connect wires to these two holes. Data pins (D+, D-) don't do anything, you only need the GND and +5V connections from the adapter board 😄

Hi @HomeKidd, third time is a charm. I finally got the third PCB up and running and even got it added to HomeKit. Sadly it only worked about 1 minute. Every time the PCB is moved (very minor like trying to triple press the button to change the display type), the power cuts out. So I guessed: The micro USB port is lose. I checked again and as far as I can tell the two small pins are still connected. Still if I attach a cable and put slowly pressure on it (like pushing up or down; it actually doesn't matter) the blue LED from the ESP lights up for a very short time and the usual high pitch tone starts for a very short time and stops right away. I can not find a cable position where it is powered for a constant time like it did for the first minute.
So you told me the two "holes" near the USB port are like a backup power supply. Can you guide me on how to use that? As I have no idea on how to fix the USB port problem (still I'm going to try a fourth time, but I'm lacking an idea what's wrong with my soldering on this). Or do you have an idea what might be the problem with my soldering here?
