Boards like ESP32-S3 Zeros (and D1 Minis, though not ESP32 😉) don’t have mounting holes, and foam tape always felt temporary to me—especially with USB plug/unplug forces putting shear on the board.

I ended up using small USB-C extension adapters as dock/mounts: they relocate the service port, provide a sturdy mechanical anchor, and let the board pop out for wiring or service. I’ve used the same idea both as an external service port/mount and as an internal service port. Epoxy provides a strong weld.

At ~$3 each they’ve been a compact off-the-shelf alternative to printed clips, with less bulk and multiple orientations available.

So far I’ve used the pattern on a thermostat, a BLE hub, and now a tiny IR blaster.

Curious if others are doing something similar, or if there are other creative mechanical mounting tricks for no-hole dev boards I’m missing.

So my 1960s condo unit has some odd but apparently normal wiring for the time - my bedroom light fixture has ONLY a load black wire and a neutral. My wall switch has ONLY a line and only a load of so textbook case for a bypass. So Shelly theoretically has a bypass for gen 3 and says it’s compatible with gen 4 - but they are like non existent availability. I’ve found a Zooz ZAC95 that by all accounts seems like it should be compatible. Has anyone tried this or does anyone have details about the Zooz that would suggest it’s the same circuit as the Shelly bypass?
