Thanks, but I already ordered 4 pieces from a local shop, they arrive on monday.

Nice they are long, 15mm! I can't find that length on AliExpress

[firened]

i wonder if the 12.5mm are sufficient too or not.

[garfield2142]

The seller responded, they should've included the risers.

I seem to have a problem with the geekworm/ugeek V3 UPS since i installed an external ON/OFF button.

It turns off randomly (on battery only) despite still having a good voltage (example 3.8V).
Somedays I'm then unable to turn it on at all despite it being plugged in.
Or it makes terrible noise (speaker on 5V).

@Garfield2142 could be similar? Let me know if you figure more what it is in your case.

Which robot is that on?

I accidentally broke off the tiny plastic on the ON <---> OFF switch, so I completely unsoldered it, and soldered new wires to an external toggle switch. If I touch any exposed metal on the UPS or the pi, it sometimes crashes. Sometimes it will just crash while charging, and the motors go crazy.

[garfield2142]

I'll take some pictures, then I'll try to resolder it

I completely removed the switch now, and soldered a tiny piece of wire to keep the UPS on permanently. Let's see if that fixes the stability issues

[garfield2142]

It seems stable now. Maybe the toggle switch wire was picking up noise that interfered with the UPS?

geekworm ups v3 occupies gpio 6 by default

[firened]

Wait - you turn it on and off using the auto-ups switch?

The extension i made is for the ON-OFF push button.

[garfield2142]

Yes, that's what I used

[firened]

There's something up with that UPS.

[firened]

Normal behavior is to use the on-off button.
The auto-ups is whether it's supposed to turn on when plugged in and empty battery ( => always on).

[firened]

What happens if you try 3s the push button with auto-ups off?

[garfield2142]

I'm not going to resolder it to auto-ups off just to test it, but if I remember correctly, it turns on and works, but if it crashes for whatever reason, it just turns off and I have to hold that button again to turn it on
