Matek MLRS MAVLink 2.4G MR24-30 receiver to mateksys mlrs mavlink 2.4G TX module
Description
1. Product Summary
1.1. Product Description
The Matek mR24-30 2.4;GHz MAVLink Receiver is a high-performance component of the mLRS (MAVLink Long Range System) ecosystem. Designed for UAVs, FPV aircraft, and telemetry-integrated systems, it provides a combined MAVLink telemetry stream and RC control link via LoRa SX1281 transceiver technology. With an integrated SKY65383-11 PA/LNA front-end and STM32G431KB MCU, the receiver achieves exceptional signal sensitivity and robust connectivity for both air and ground applications.
1.2. Key Features
- Based on open-source mLRS firmware (MAVLink Long Range System).
- 2.4 GHz ISM band operation using LoRa SX1281 with TCXO for high stability.
- High output power: configurable 13 / 20 / 24 / 27 / 30 dBm (up to 1 W).
- Integrated SKY65383-11 PA/LNA module for enhanced range and signal quality.
- Supports full-duplex MAVLink telemetry and RC output (CRSF/SBUS).
- Compact form factor: 28 × 21 mm; lightweight (~4.5 g with antenna).
- Power input range: 4.5 – 13 V DC.
- Equipped with LED indicators for link, binding, and operational states.
- Compatible with Matek mR24-30-TX and other mLRS transmitters.
- Firmware upgradable via DFU or STM32CubeProgrammer.

4. Applications
- UAVs; Drones: Long-range bidirectional telemetry and RC control link.
- Fixed-Wing Aircraft: Reliable long-distance communication for flight control and monitoring.
- FPV Systems: Integrated control and MAVLink data for telemetry overlays and ground stations.
- Research Platforms: Ideal for test setups requiring stable, configurable RF links.
5. Installation; Configuration
- Connect power supply (4.5 – 13 V DC) to the “V” and GND pads.
- Attach the antenna securely to the IPEX MHF-1 connector before powering on.
- Link the receiver with a compatible mLRS TX module (e.g., Matek mR24-30-TX) via binding mode.
- Use the mLRS Configurator or STM32CubeProgrammer for firmware updates.
- Configure MAVLink and RC output channels per flight controller (UART mapping for TX1/RX1, TX2).
- Ensure proper RF separation from power electronics and carbon structures.
6. Practical Summary
The Matek mR24-30 Receiver delivers a powerful and flexible 2.4 GHz link combining RC control and MAVLink telemetry in a single compact module. With configurable power up to 30 dBm, LoRa-based transmission, and open-source mLRS firmware, it provides excellent range, stability, and integration for advanced UAV, FPV, and autonomous systems. Perfect for developers and integrators requiring reliable, high-bandwidth communication in demanding environments.
