## Overview

The Matek 3901-L0X module combines PMW3901 Optical Flow and VL53L0X Lidar sensors to deliver precise altitude and motion data for RC FPV racing drones. Supporting UART MSP V2 protocol, it integrates seamlessly with INAV and ArduPilot firmware. With a compact 36x12mm form factor and ultra-low 40mA power draw, it offers a working range of 8cm to 2m and fields of view optimized for stable flight control. Ideal for professional drone pilots seeking enhanced navigation and obstacle awareness.

## Description

This module works with INAV firmware(2.2.x or latest) onlySpecifications: Optical Flow: PMW3901 Lidar: VL53L0X Interface UART Protocol:INAV MSP MSP Working Range: 8cm~200cm Field of view: 42 degree(PMW3901), 27 degree(VL53L0X) Minimum Illumination >60Lux Input voltage: 4.5~5.5V Power Consumption: 40mA Size: 36*12mm (F051 version), 2g Size: 36*13mm (L051 version) 2g Tips: Make sure Optical Flow lens to ground >2cm for opflow initialization while FC starting up. Maximum range of VL53L0X is 2m, Altitude hold 0~2m @ throttle 0~100% if VL53L0X is enabled. Any unused UART of FC supports it Sonar connection (Trig & Echo) has not been implemented If your flight controller doesn’t have a barometer detected, you won’t be able to select “NAV ALTHOLD” in modes tab. Packing: 1pc Module 3901-L0X

Review: Rangefinder weak, optical flow fine - Does not reliably sense the distance above 50 cm, while competing rangefinders sense 150 or 200
