I don't understand how you can power all of these at full power when the input voltage is a single ~30v DC wall adapter? Isn't that your bottleneck right there?

- KeplerBoy 3y agoThat's not the issue. 24VDC power supplies with tens of amperes are not hard to find, they won't be wall warts though. I'm not sure though, if the board can actually put out high power from all 4 ports at the same time. Does anyone know?
- dclowd9901 3y agoThe supply wire looked like 14awg-ish which seems a little dinky for 20a @12v

- dclowd9901 3y agoI mean, as someone who’s wired entire camper vans, I can tell you that I wouldn’t put 20 amps through 14awg, but I guess it also depends on the wire.
- popol12 3y agoWell, I guess that's the difference between "chassis wiring" and "power transmission" in the table at https://www.powerstream.com/Wire_Size.htm https://www.powerstream.com/Wire_Size.htm It's about how long your wires are going to be, and a desktop electronic project has at least orders of magnitude smaller cable than a van, I'd say.
- undersuit 3y agoHow many amps? Genuine question, I can't find the info.
