Happymodel EP1 Dual RX ExpressLRS receiver
Happymodel EP1 Dual RX is the very first full diversity ExpressLRS receiver in the market. It has two independent SX1280 RF chips, with individual PA/LNA RF amplifiers. This allows to listen to both RF chips at once and receive packets from whichever one is getting them reliably.
This is much better than antenna switching, where receiver doesn’t know which antenna to listen on and only can “guess” based on the last packet it got.
Telemetry output from Happymodel EP1 Dual receiver is 10-20dbm and is selectable from Lua script.
There have been rumors about the dual channel RC link that will help in congested RF environments, such as at races to provide more stable and robust RC link. Happymodel EP1 Dual RX would be able to support that.
