Hi. What DC convertor part do you recommend for coverting the battery output for RPi 5?

Is this a good option?

THN 30-4811WI

There is also an adjustable version, but I’m not sure if it’s necessary.

Hi @malizade

We use a PCB with a custom SMPS on the board. More infos about this board should be available soon.

I think your DC/DC should be good in term of power.

Hi @malizade, does THN 30-4811WI work for you? I am using RPi5 with THN 20-4811WI, but the RPi5 shut down while running the code.

Hi. I just recently assembled the PCB and ran a stress test code. CPU temp went from ~50 to ~80 C. The RPi did not shut down, and the power converter itself got warm but not particularly hot.

So by this metric, it does seem to be working so far.

Thanks for the question and great discussion! We have recently released a new embedded system that does power management for the Raspberry Pi CM. We hope to be able to enable groups to purchase these from us within a month or so.
