MicoAir MTF-01P Optical Flow & 12m Range Sensor

The MicoAir MTF-01P is an integrated optical flow and time-of-flight (ToF) rangefinder module designed to provide rock-solid indoor position hold and low-altitude terrain following when GPS signals are unavailable. Engineered for custom ArduPilot and INAV builds, this lightweight sensor allows multirotors to maintain stable hovering and navigate safely through complex, confined environments or dense tree cover where satellites cannot reach.

Key features

• Integrates a wide-angle optical flow camera and a high-accuracy ToF LiDAR to enable stable autonomous hovering without relying on GPS lock.
• Outputs data over a single UART at 115200 baud, with selectable MicoLink, MAVLink (ArduPilot or PX4) and MSP (INAV) protocols for clean, single-cable flight controller integration.
• Extends altitude holding capability up to a 12-metre ceiling, making it highly effective for warehouse surveying, tunnel inspections, or indoor cinelifter flights.
• Pre-configured firmware ensures straightforward plug-and-play compatibility with modern flight control boards straight out of the box.

For successful configuration, ensure your flight controller runs a recent firmware version (ArduPilot 4.3+ or INAV 5.0+) that natively supports incoming MSP optical flow and rangefinder data. Ensure the downward-facing lens remains clear of debris and is mounted securely away from major frame vibrations.
