HelloRadioSky HREP ExpressLRS ELRS 2.4GHz High Refresh Rate Open Source Receiver for FPV Racing Drone
Description: The HeIIoRadioSky HREP receiver is based on ExpressLRS, an open source RC link for RC applications. ExpressLRS is designed to achieve better link performance in terms of speed, latency, and range. This makes ExpressLRS one of the faster RC links available while still providing long-range performance.

Dimensions: 11*19*3mm Telemetry power: 20dbm Frequency band (2.4G version): 2.4GHz ISM Input voltage: 5V Antenna connector: IPEX MHF Antenna type: 18cm high-sensitivity dual antenna Wireless protocol: Pre-installed ExpressLRS 3 3.0 Maximum receive refresh rate: 500Hz Minimum receive refresh rate: 25Hz Backhaul power: 100mw Working protocol: CRSF
It took me a while to understand, that the pin order of RX and TX is different from all my other receivers. Eventually i got them working. The soldering quality is ok considering the price.

Q:
There is no output signal, what can I do?_It is bound to the radio (latest ELRS firmware)_It is connected to the radio_Telemetry data from flight contoller are properly transmitted to the radio_Protocol is CRSF_Output mode is serial_But the TX ouput is contanly at 2.0V_Any ideas?
There is no output signal, what can I do?
It is bound to the radio (latest ELRS firmware)
It is connected to the radio
Telemetry data from flight contoller are properly transmitted to the radio
Protocol is CRSF
Output mode is serial
But the TX ouput is contanly at 2.0V
Any ideas?
Ok, I found the problem. The pinout of this receiver is different from normal. RX and TX are swapped. It is a real pain, when soldered to a board via pinheaders.
