For pre-production (beta) boards, this is possible by following [this guide](tutorials/wiring/easy-piezi/unregulated-operation/) + +**Q:** Is it required to use the SingleDisk Piezo Adapters? + +**A:** No. the SingleDisk adapter board is simply a carrier for a 12mm piezo disk that has the dual benefit of maximizing signal-to-noise ratio, and providing a consistent mounting scheme. All that's required is a piezelectric element that has positive and negative rails that can be connected to the Pyr0-Piezo circuit. \ No newline at end of file
