STD ExpressLRS & MPM-CC2500 Jumper T-Lite
License: GPL 3.0
Mode: Editors' pick
Combined ExpressLRS and Multiprotocol CC2500 internal module for Jumper T-Lite. MPM is connected to the internal module breakout, ExpressLRS to external. An RF switch is used to operate with only one antenna. All the MPM curcuitry is supposed to lose power and the RF switch to use ExpressLRS input if the external module breakout is powered.
Inspired by and partially based (at least board geometry) on jyesmith's https://easyeda.com/jyesmith/expresslrs-jumper-t-lite. Never implemented yet.
