SubGhz support

Support for SubGhz tags can be added by connecting an CC1101 module to the T-Panel via the H2 expansion port accessible externally.

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.

Important

Don't forget to attach an antenna to the Ebyte module! Any antenna for the 868/915 Mhz band with an UFL connector is fine.

This is one example.
