The LiteWing Drone Positioning Module is a plug-and-play optical flow and ToF-based stabilization add-on designed for indoor and GPS-denied flight. Featuring the PMW3901 optical flow sensor for precise X/Y position tracking and the VL53L1X Time-of-Flight sensor for accurate height measurement, this module enables stable height hold and position hold performance. Ideal for DIY drones, autonomous flight experiments, and educational robotics projects.

To make your development easier, the LiteWing Drone positioning module comes with its dedicated wiki page and tutorials to cover the basics to advanced concepts, and help you understand the basics and build your own cool projects

Important: The PCB colour of this module might be in black or green depending upon the time of purchase. The functionality and features will remain the same regardless.
