Solum 2.2 inch Electronic Shelf Label Teardown
Quick peek inside the EL029F3WRA
In light of the recent news that the OpenEPaperLink firmware has been ported to the nRF52811
series of chips, I decided to take a look inside the Solum EL029F3WRA to see if it was a viable candidate for a project.
As it turns out, it is very similar to the 2.9 inch tags. I hope to soon have a simple CAD model of the ESL which I’ll use to model a basic pogo-pin programming jig for this particular ESL.
