This is a PCB for the OpenEPaperLink AP and Flasher! Quite a lot of boards in this PCB actually, you can use them to build flasher jigs for a few different tags. You'll need to add some components, such as a case, an ESP32, and some other items. The quantity is pretty dependent on the type of jigs you want to make.

It's made out of Black 1.2mm FR4, and it's ENIG-treated.

Please check if this is something you can use; you'll need to do some SMD soldering (1206-sized components). You'll need to print a case yourself, and you'll need to program you S3 yourself. There's not a lot of support on this (it's on best-effort basis), I'm basically providing PCBs so that you won't have to order an entire batch yourself. Please please pretty pleaser check the link below before ordering, and see if you can still get everything you need.

You can find a list of components here

Note that an espressif-S3-DevkitC1 doesn't fit without bending some pins. The bootleg ones from eBay do!
