MATEKSYS mLRS 2.4GHz Receiver (MR24-30)

The MatekSys mR24-30 is a dedicated 2.4GHz receiver engineered for the open-source mLRS radio control system. Designed primarily for autonomous drones, fixed-wing cruisers, and long-range UAVs, it leverages LoRa modulation to provide a robust control link alongside high-bandwidth, bidirectional telemetry.

Key features

• Native support for the open-source mLRS protocol, offering true full-duplex communication.
• Transmits bidirectional MAVLink telemetry directly to your ground station, eliminating the need for standalone radio modems.
• Supports standard CRSF serial output for cross-compatibility with flight controllers running INAV or Betaflight.
• Operates on the 2.4GHz ISM band, delivering long-range LoRa penetration with a compact antenna footprint.
