Recurboy rebooting while working

Hello, today I received the assembled Eurorack Recurboy module. I ordered it from Perfect Circuit.

I installed it in the case, and at first it wouldn’t start at all, just a white screen and the Raspberry Pi rebooting every 30 seconds. It was as if it didn’t have enough power to boot up. I started removing modules from the case, and eventually the Recurboy started up. I started adding other modules one by one to find out how many it would take before the power supply became insufficient. In the end, I put all the modules back in place and they all worked, but after about an hour, the recurboy started rebooting again, but not as often. It would turn on, work for 3-4 minutes, and then reboot again. I also tried connecting a webcam via an adapter, and an image appeared for a second, then it rebooted again.

I don’t quite understand what this problem could be related to, since, apparently, there is enough power for it to work in general. Considering that I couldn’t find any power consumption specifications for recurboy, I’m a little confused. As far as I understand, it mainly consumes +5V, and there is another fairly power-hungry mainbow module in the case, but they start up and work together; the problem at the moment is only with recurboy. The other modules consume very little, mainly simple LFOs and envelopes.

Has anyone measured the peak power consumption for recurboy or encountered a similar problem?

i don’t know the specifics of how the eurorack version of recurboy converts eurorack power to the 5V that the raspberry pi zero needs, but i know that with raspberry pis in general, a boot loop can definitely be the result of insufficient power.

I removed all other modules, the power supply reserve at +5V should be about 1A, which I think should be more than enough.
It works for 5 minutes and then reboots again…
I tried powering it from a USB cable, and it works stably, but for some reason it does not transmit the signal via the composite output.
Is it just me or something working wrong?

i’m seeing this post but i’m not sure of the answer. powering the pi separately does seem like it could help stabilize things but i get the appeal of eurorack, single power supply. and it’s annoying cause it should work. hopefully someone else will know more.

Do you know the peak power required for correct operation? I believe that in Eurorack it should be the same as when using an external power supply.

i think the peak for the pi alone would be 1.2 amps. then for the rest of the components i’m guessing you would want to increase that to be safe but not sure by how much
