Matek mLRS 900MHz Receiver MR900-30

The Matek mR900-30 is a 900MHz mLRS module built for ArduPilot and PX4 long-range builds, carrying RC control and MAVLink telemetry over a single openly-developed radio link.

Key features

• Runs the openly-developed mLRS protocol on the 900MHz band for long-range, low-interference links.
• 30dBm output extends control range well beyond standard 2.4GHz RC links.
• Carries RC control and MAVLink telemetry on one radio link, simplifying long-range wiring.
• Suits mapping, survey and long-range fixed-wing or multirotor builds running ArduPilot or PX4.
• 900MHz band penetrates obstacles and foliage better than 2.4GHz, helping range on low-altitude flights.
