RE: Raspberry Pi 4 vs. 3B+ first impression

Posted by zacster on September 14, 2020 at 20:03:19:
So a quick update. I finally got a USB-A to USB-C cable so I could power the Pi from the battery and it really sounds better that way. The DAC was already powered by the same battery. The prior method was the Pi was powered by a the 3amp switcher that came with the Pi 3B. I just happened to have an adapter for that. Between USB-A, micro USB, USB-C and barrel connectors there sure are a lot of different ways to supply 5v.

The other thing is I also bought a heat sink/fan case for it from MazerPi. I was worried about the fan drawing too much battery power but it doesn't, and also making noise, but I had to put my ear up to it to even hear it. It's a much nicer case than the plastic ones I had for my 3Bs. It is a real heat sink.
