2.4G ExpressLRS EP24S SP24S Long Range Receiver MINI RX ESP8285 MCU SX1280IMLTRT RF For FPV Racing Drone Tinywhoop

EP24S/SP24S 2.4GHz ELRS series receivers are 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, it will take a while. Find the ExpressLRS hotspot, connect to this hotspot through a computer or mobile phone, the connection password is expresslrs, it will automatically enter the upgrade page, if not, 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.
Since the ELRS receiver uses a low latency and high refresh rate RF chip, 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 contents of the receiver firmware of each manufacturer are basically the same, but the name is different (except BETAFPV, the circuit is different).

Linking steps:
1. After the receiver is connected to the flight controller, connect the USB to power the flight controller. After inserting the USB for the first time, disconnect the USB as soon as the LED on the receiver turns off. Repeat the operation twice, when the USB is inserted for the third time, the LED will start to flash double, and the receiver will enter the code matching mode.
2. After correctly connecting the 2.4G ELRS tuner module and the remote control, copy the ELRS.LUA file to the SD card in the remote control, the directory is SD Card/Scripts/tools, and then run ELRS.LUA for Bind operation.
3. After the binding is successful, the LED on the receiver will become steady on, and the telemetry signal can be received at the same time.
