This is an alternative firmware and protocol for various Electronic Shelf Labels (ESL). It can be used to setup E-Paper (EPD) tags and supply them with content.
The software in this project consists of two parts:
Additionally, there are various hardware designs for access points and flasher-interfaces to program tags, preferably using one of the many programming jigs.
Caution
While considerable effort has been spent researching all of this, most of the information here has been gathered from the tags themselves, information in the FCC database, or extrapolated from other sources. Since there is very little information out there this is the best we can do. We probably got some stuff wrong ...
Please help and add additional information wherever possible
Feel free to add missing information, write documentation, tips or tutorials.
