Anyone interested in a USB-C PD presentation (by me) for February?

[Nathan Lewis]

Hey all!

I've seen a large quantity of threads surrounding USB-C PD in the last year, is anyone interested in a deep-dive into USB-C PD and how to work with it for our February presentation?

I'm thinking this is relative to the Pi 5 for the most part. I'd be interested!

Perhaps pair it with another "mini presentation." I don't know that we need a whole hour on USB-C PD.

Thanks,

Camp

Hi camp, the presentation would be on a project I've doing that I'm tentatively calling the "BotPDU". It's basically a USB-C PD power bank with extra features that make it more useful in robots. (such as also having DC-out(s) with programmable voltage/current limits you can connect to ESCs, servos, etc. along with the USB-C PD outputs)

Is it online if so possible to share the link? Thanks 😊

Haven't written anything down yet, hence my curiosity about whether anyone would be interested in me doing so at all =P.

PD is potentially very useful for robots. Many times the motors work at a higher voltage. The motor driver could ask the PD power supply for whatever volts is required and for the current to be limited to whatever the motor and wire are rated at. Could remove the need for all those DC/DC voltage converters. So one side is a bunch of PD outputs and they all connect to a large LiPo bank. This makes sense, but I did not think of it until reading this. Thanks.

I think what people might want to know is how to use the chips that enable PD.


I actually planned to do something like this with my 3D printer. The print head has some electronics, LED lights, and of course, a heater to melt the plastic, and I want to convert to a system where only one USB-C cable goes to the print head. Currently there is a thick bundle of wires. It could all be replaced. I’m looking at multiple print heads on the one printer and I need to reduce the cable bulk first. The same logic could apply to robots. Power and data over one cable is very attractive.

Nathan, Sure  it’s certainly a significant topic of interest these days with a dose of its share of discussions. Ross

Yeah, this sounds good! 🤖👍
