Equipment

This is everything I have used and tested, and most of it is stuff I find useful.

Power

60 Port USB Charger

Yeah. That’s 60 ports. Funny enough, if you’re using Pis, you’re more likely to run out of amps than ports, since this thing maxes out at 60A. For most of these low-end devices that’s fine. If you need more, they sell a higher capacity model. Just be warned, that higher capacity model is 140A (!!) and runs on 240V (!!!!).

USB C Charger

For some devices, USB PD is more important than 5V. The Radxa Rock5B is one example. This little thing has enough juice for two, provided you use the right cables.

PoE+ to 5V USB-C/Barrel adapter

I use this with my XU4s to turn them into PoE powered devices I can put anywhere.

Other Hardware

Pi-like Device x4 Rack Mount

A simple rack mount for 4 devices that share the Raspberry Pi B footprint. I use this with my Rock64s.

Storage

Endurance MicroSD Card

I’ve used these for a while. They’re fast, cheap, and haven’t died on me yet.
