How is it that USB PD 3.1 PPS is shipping in hundreds of products and nobody has made a simple box that takes USB C input, 2 banana jacks output, and provides a knob and a 7 segment display to set the voltage. Come on I don’t want to have to roll my own

@s0 a few of us ( @voltagex @Unixbigot et al) are thinking about the other end of this - a battery bank with a bunch of high-power outputs that all have power displays, also displaying over Bluetooth, so you can run a phone, a laptop, a soldering iron, a hotplate, and a couple of devices under test from it.

@jpm @s0 @voltagex @Unixbigot I flashed back to this post as soon as I saw "a knob and a display"

https://aus.social/@jpm/113223527572107152

Then I remembered I bought one back when you posted that and I can't recall where I stashed it ...

@s0 I know there's been a few options sent to you. Here's an expensive option, but then again, it does a lot: https://www.fnirsi.com/products/dps-150

@Unixbigot @voltagex @jpm it’s cool, but not PPS — this is doing a second stage of switchmoding in the PSU.

I’m looking for something that is effectively just a front end — a screen, a knob and a microcontroller (well, and an LDO to run the MCU I guess!)
