With the board extracted, we can see the sensor assembly and another significant missing component for a 2019-2020 mirrorless camera, no IBIS. The fp does make use of electronic stabilization for video as well as stabilized lenses, but there is no bulky sensor-shift stabilizer like you’d find int the A7 and Z series in this camera. The sensor itself rests on shims for its factory alignment. We can also observe another pair of thermal pads to the right.
Once the sensor is out, you can see clean through to the other side since there is no mechanical shutter!
