Product Details

The EP24S 2.4GHz ELRS series receiver is based on the open source architecture and program of ExpressLRS. The receiver uses ESP8285 MCU, so you can upgrade the firmware through WIFI. As long as the receiver is powered on and the remote control is turned off, you can find ExpressLRS after a while Connect to this hotspot through a computer or mobile phone. The connection password is expresslrs and it will automatically enter the upgrade page. If you don’t have one, you can manually visit 10.0.0.1 to upload the receiver firmware. Of course you can upgrade the firmware with general flight controller and external USB-TTL.

Because the ELRS receiver uses low-latency and high-refresh RF chips, it is very suitable for FPV competitions and remote FPV. At the same time, these receivers have ultra-light and ultra-small sizes, so they are very suitable for Tinywhoop.

Regarding the choice of receiver firmware, our default shipment is DIY_2400_RX_ESP8285_SX1280. The receiver firmware content of each manufacturer is basically the same, but the name is different (except BETAFPV, which has different circuits).
