I am a complete beginner in Pi.
I am trying to set-up an audio streamer with Volumio and a touchscreen + a on/off button.
My set-up is working perfectly without the power management (RS-50-12 Power supply + Pi-SPC + button) when plugged to the USB-C power.
When I plug the power management set-up to the Pi, It starts but then… white screen, grey screen, blincking and then… nothing more. It looks like it is rebooting and then dead. A video is easier than lots of words
Here is a sketch of my set-up (I haven’t found an esay tool to draft the set-up.)
Hi, do you power a Rpi4 + (large) screen + audiohat with a standerd 3A power supply? You should try to measure the actual power delivered to the setup. All these devices combined indeed may lead to a power drop that interferes with the boot process. I have struggled with the same issue in the past. Only the use of a solid SMPS (in my case a Nirvana from Allo) could solve the issue. Can the screen be powered separately?
Indeed it works with a traditional USB-C with all components.
However ion my set-up, I want an On/off button and I could’nt find a way to have it wioth this kind of power supply. That’s why I bought PI-SRC and the extra Power supply.
If you know how to have a on/off button (physical, not within volumio) with the traditional USBC, I am your guy
