Product Details
This is a small and affordable way to add position hold functionality to your UAV without the need for GPS. It has a working range of up to 2m, and uses a VL53L0X Lidar rangefinder along with a PMW3901 optic flow module. It connects to your FC via UART and it currently supported only by INAV, but other firmware projects like betaflight will support this in the future.
