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).
The SP24S and EP24S use the same receiver hardware, except the EP24S uses and includes a T-Antenna connected by U.FL The SP24S uses a built-in ceramic antenna. Both receivers come with wire sets.

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.
