There is no support in the firmware for the sonar module.  There is a developer working with the hc-sr04 modules but nothing is released.

External mag is talked about in the gps wiki article, https://librepilot.atlassian.net/wiki/display/LPDOC/GPS+setup and in a separate article at https://librepilot.atlassian.net/wiki/display/LPDOC/Aux+Mag+Setup+and+Calibration

Is it a limit of librepilot or of revolution board??other firmware can support sonar hc-sr04?tnx

It's a limitation of not yet being implemented in firmware.

There is a development branch with sonar support https://bitbucket.org/TheOtherCliff/librepilot/branch/theothercliff%2FLP-225_sonar_support
Although flyable and Cliff was showing some movies how it performs, it's still work in progress and not yet merged with next (yet).
