2pcs of ELRS CRSF to SBUS Converter Compatible with CRSF/SBUS Protocol Receiver, Support CRSF to SBUS, or SBUS to CRSF Conversion

Was able to successfully connect a Radiomaster Zorro Tx ==> ELRS receiver soldered to this adapter ==> connected to SBUS pad on a F4 flight controller as a test.The F4 FC receiver tab in betaflight was set to serial Rx / SBUS. All 9 of my already specified channels responded correctly.Was not successful in updating the firmware of the Matek adapter board - see Matek website."mateksys-dot-com/?portfolio=crsf-sbus" for wiring and firmware update.Have not tried connecting the Tx of the FC UART directly to the ELRS receiver Rx pad to see if telemetry data could be sent back directly from the FC to the ELRS receiver, bypassing the SBUS converter.Website states:Battery voltage(RxBt) telemetry over CRSF protocolCRSF to SBUS latency <7msAn inexpensive way of getting an ExpressLRS transmitter to communicate (at least) unidirectionally with an RC SBUS environment.

Worked great for me.
