Intrest Survey: E-Ink Name Tag

<< < (5/5)

bitwelder:
If the idea is to use it as a 'name tag' (i.e. a text that doesn't change that often), I'd split the project in two parts:
1) the e-ink screen itself with a simple (and lightweight!) plastic frame, and its contacts semi-exposed maybe as a string of PCB pads. No power needed here.
2) a programming 'jig', with all the STM32 logic, the USB/Wifi/whatever interface, power input, and some kind of pogo-pins where to plug the screen module just for the time to set its contents.
So you need to make only one jig to serve potentially a number of e-ink modules.

That would be a good move, bitwelder. Except I would suggest sliding contacts for the programming jig rather than pogo pins - perhaps a PCB edge connector type (but thinner, single-sided). Reason being that you could then have a module which mounts the display, for portable wearable purposes, and uses the programming pins to change the screen whenever buttons are pressed or whatever. Pogo pins would work but add depth.

Yess. I agree. Pogos are also a little fragile to use outside a lab environment.
