Which PCB gyro board? When I think of "PCB gyro boards" it is typically a commodity chip like the MPU-9250 packaged on a board with the necessary filtering caps, etc, There is not any firmware to modify really, all of the processing is done by a separate MCU that handles the filtering and processing.
