PDM info dump

Everyone loves a good distraction right?

Radlok RL00571-25 https://www.amphenol-industrial.de/en/RL00571-25/5-7mm-Radlok-plug-25mm-orange/p10796 is an alternative to good old 6mm stud

VN7003ALH sounds cool fun fact: today dev board costs $4 while single chip costs $5. A modern replacement for legacy AUIR3313S?

https://digitalcommons.calpoly.edu/eesp/387/ would be a source of inspiration

Need help: looking for off-the-shelf hardware for positive terminal. We want a flange touching PCB and we want an eyelet outside of the case.

TDG went with everything custom including 11 head m6 internal low profile nut I would prefer to go with simpler stuff.

Let's start with M6 options?

Maybe wurth 7461098
Maybe wurth 7461084

random cool not M6 stuff

Let's KISS and prototype with a brass bolt https://accu-components.com/us/12-pan-head-screws?Material=Brass&Thread+Size+%28T%29=M6+%286mm%29&page=1

A simple screw is actually less simple - a screw through a PCB will creep he fiberglass, making the board thinner, progressively making the connection worse.

The VN700x are decent parts. I am using them as a replacement for the marked-for-obsolescence VN5E010AH. I have a couple thousand of them right now because.... I could buy them. Supply is *extremely* limited.

The Weurth terminals are also awesome. They're very well designed. I think I am using a M5 one? Availability is kind of icky sometimes. TME seem to do a very good job of stocking them, if you don't mind shipping from Europe.

Another source of high-current lug stuff is lugsdirect.com
They have a lot of bizarre and interesting parts.

I've tried some of their "SMD" parts (i.e. https://lugsdirect.com/B2C-PCB-SS-Surface-mount-tech-2-14AWG-115A-PCB-terminal.htm ) and have found them to be too easy to break off PCBs in the course of securing wires.

The slotted/TH parts (i.e. https://lugsdirect.com/B6A-PCB.htm ) are very good quality. Great value.

Note: these are *hard* to solder with just a regular soldering iron. Even with a 100W professional iron, you need to do some pre-heating. The parts just soak up too much heat. Wave solder with a little pre-heat? Butter. Excellent coating.

Also older MC33984/MC33988 - dual channel direct or SPI control. AliExpress has them at fairly decent price.

ETA makes SCS200 PDM.

It is PDM without any brains, controlled by can messages.

Put together Google drive folder with datasheets, manuals and CanHacker TSK file.

Would a latest and greatest VN9008AJTR be cool on a PDM? Pretty available right now.
