    I'm interested in using this board to build a GPR for concrete, and drywall. What frequency is the board setup to scan at? Can it do that?

    Hi Sargun,

    X4 has to different frequency bands, with center frequencies of 7.29 GHz or 8,75 GHz, both wit an bandwidth of ~1.4 GHz, see the X4 datasheet for details: https://www.xethru.com/community/resources/x4-datasheet.106/

    Higher frequencies will give less penetration, here is an app. note showing penetration through some building materials when the sensor is in far field: https://www.xethru.com/community/resources/signal-attenuation-from-building-panels.65/

    See chips+salsa for solutions supporting lower frequencies:
