Std EditionWIP ExpressLRS espC3 RX FD
Profile：Testing a new design for ELRS receivers
License: CERN Open Hardware License
Project source： Cloned from WIP ExpressLRS esp8285 Rx
Description
WARNING: The schematics on the project home page seem to update somewhat randomly. Make sure to open the actual project to see the latest schematics.
NB While this is intended to be a new generation of ELRS receiver it is not compatible with existing receivers, nor is it supported by the main project. Code for it is in my fork of the elrs handset project.
