+This is an alternative firmware and protocol for the multiple Electronic Shelf Labels. It can be used to setup E-Paper tags and supply them with content.
 
 The software in this project consists of two parts: Accesspoint-firmware and Tag firmware.
 Additionally, there are various hardware designs for accesspoints and flasher-interfaces to program the tags, preferably using programming jigs

-## Compatibility
-It is currently compatible with the following tags:
-* 4.2"
-* 2.9"
-* 1.54"
-* Segmented (work in progress)
-
-On the 2.9" tags, both the UC8151 and SSD1619 display variants are supported

 ## Aims
 - Low power (currently around 9µA with a minimum of 40 second latency)
 - Even lower power when there's no AP around
