# Sensor Support

The following table was machine generated by [find_sensors.rb](assets/find_sensors.rb) script on %s against INAV %s, E&OE

Targets suffixed by \* indicates that there are (probably) multiple hardware variations covered by one or more firmware images (or just a strange target.h). Additional, related targets are listed in parentheses. The user may check the hardware documentation (or `target.h` / `CMakeLists.txt`) to determine the actual supported sensors.
