We are now launching ER5 Series ELRS PWM receivers. ER5A ELRS PWM receiver for Aircraft applications, and the ER5C ELRS PWM receiver for surface & marine R/C applications. 

Developed around the ESP8285 MCU and SX1280IMLTRT RF Chip the RP series offer Lora and FLRC 2.4ghz RF links offering incredible range and low latency. With Wifi built-in FW updates can be done on your craft without the need to remove the receiver. Binding can be done using a bind phrase meaning no more bind plugs or fiddly button presses while trying to plug in your battery.
