The infrared optical flow ranging module is a new infrared short-range measurement solution launched for fields such as drones.
This product is based on the dToF ranging principle, with small size, low cost, and excellent performance. This product is based on UART or I2C communication to transmit distance information, simple to use, flexible to install, and easy to expand.

Supports multiple open source firmware, PX4, INAV, Ardupilot, Betaflight AUTO protocol open source adaptive, UART, I2C private protocol can be adapted to USB to TTL data cable connection module can be freely changed to the required protocol type, direction does not require downloading from the upper computer, one-stop solution for problems
Protocol modification address: tof. corvon.tech
I2C is a proprietary protocol and does not support open source
Note:
If the flight control is PX4 firmware, selecting AUTO protocol only supports firmware below PX41.16. For firmware above 1.17, please contact customer service to modify it to PX4 fixed protocol
Betaflight firmware requires the latest version from 2025
Only versions 5 or above can be supported
