Technical Highlights

mLRS MAVLink and RC Link

The mR24-30 is a 2.4GHz mLRS receiver for bidirectional serial MAVLink and RC data. TX1/RX1 carries MAVLink, while TX2 provides a configurable CRSF or SBUS RC output. This module does not transmit FPV camera video.

Selectable RF-Link Power

The manufacturer lists 13 dBm minimum, 20, 24, 27 and 30 dBm RF power settings. The 30 dBm rating equals 1000 mW and is the maximum listed mLRS radio-link setting, not a continuous video-transmitter rating.

LoRa Radio Hardware

The board uses an STM32G431KB MCU, an SX1281 LoRa device with TCXO and an SKY65383-11 PA/LNA. Its antenna connection is IPEX MHF-1.

Compact Receiver Board

The PCB measures 28 × 21 mm and is specified at 4.5 g with antenna. A separate heatsink is listed by the manufacturer for higher-power operation.

Installation Notes

Supply 4.5–13 V DC to the V pad and connect G to ground. Verify the flight-controller wiring before applying power.
Use TX1/RX1 for bidirectional serial MAVLink and TX2 for the selected CRSF or SBUS RC output.
Attach a suitable 2.4GHz antenna to the IPEX MHF-1 connector before RF operation.
For RF power settings of 500 mW or higher, MATEKSYS recommends attaching the heatsink to the bottom of the PCB.
Use the receiver-specific firmware target when updating a unit intended to operate as an mLRS receiver; confirm the installed firmware and configuration first.

FAQ

Is the mR24-30 a video transmitter?

No. It is an mLRS radio-link receiver for MAVLink and RC data. Its RF power settings do not describe FPV video transmission.

Is 30 dBm the only RF power setting?

No. MATEKSYS lists 13 dBm minimum, 20, 24, 27 and 30 dBm settings. The 30 dBm setting is the highest listed value and equals 1000 mW.

Which connections carry MAVLink and RC data?

TX1/RX1 provides bidirectional serial MAVLink. TX2 provides RC output configured as CRSF or SBUS.

When should the heatsink be fitted?

MATEKSYS recommends fitting the heatsink to the bottom of the PCB when RF power is set to 500 mW or higher.

B2B Procurement FAQ

What should be confirmed before ordering?

Confirm the mR24-30 receiver model, installed mLRS firmware, required receiver configuration, antenna and heatsink contents, and the intended MAVLink and RC output settings in the quotation.

Which firmware target applies to receiver use?

MATEKSYS lists rx-matek-mr24-30-g431kb as the receiver target. The same hardware has separate TX-mode targets, so confirm the intended operating mode before flashing.

What are the MOQ, lead time and warranty terms?

These terms are not established by the supplied product files and must be confirmed during quotation.
