Adding SubGhz support to LilyGo T‐Panel AP - OpenEPaperLink/OpenEPaperLink GitHub Wiki
NB: SubGhz support is NOT functional in the current release, but Beta binaries are available here.
The LilyGo T-Panel S3 is a standard off the shelf product from Lilygo which can be used as an OEPL AP without modifications with 802.15.4 and Bluetooth based tags.
Support for SubGhz tags can be added by connecting an CC1101 module to the T-Panel via the H2 expansion port accessible externally.
SubGhz can be added to both the RS485 and CANFD versions of the T-Panel, but NOT the "Lite" version since it does not include the H2 expansion port.
SubGhz Connections for LilyGo T-Panel S3
An CC1101 module can be connected to the H2 expansion port using a 16 pin ribbon cable with a 1.27mm / 0.05" pin spacing.

An PCB is planned to replace the need for spaghetti wiring.
NOTE: Pin 1 is the lower right hand pin looking at the back of the T-Panel with the USB connectors at bottom.
