Finally the pcb for my version of the Cheap-O hall endstop sensor turned out as I wanted.
The two slots are for wire strain relief so the soldering and copper wont get pulled.
The first soldered and tested, and works exactly as expected!
This is also around the distance from where it detects the magnets (varies depending on the magnet strength).
If you forgot how accurate it is, you can have a look at this post “End stop tests“.
Now there is only one thing left, to make them available for sale and there is good news! makerstoolworks.com has shown interest in them and is going to make a bunch of them. So jump over to their site and sign up for the email notification about when the shop open. 🙂
