This is a nano sized receiver for the ExpressLRS ELRS system.   The EP1 is based on the ESP8285 MCU that allows for upgrading via WiFi.  This version includes an IPEX connector for external antennas for improved range.

Detailed Information

Please note, ELRS is a new open source project so please only order this if you are comfortable with regular firmware updates as the firmware is still in beta.  We will only be able to offer limited support due to the early nature of the firmware, but we think this project has great potential.
