**Q:** Pyro-Piezo? EasyPiezi? What's the difference?

**A:** Pyr0-Piezo refers to the circuit that utilizes Piezoelectric Elements to perform auto bed leveling on 3d Printers, while the EasyPiezi is a standalone board dedicated to carrying this circuit. The Pyr0-Piezo circuit can be integrated into other boards and designs, such as the Pyr0-Piezo FFC.

**Q:** What's the difference between the EasyPiezi and the Pyr0-Piezo FFC?

**A:** The Pyr0-Piezo FFC allows the user to replace their existing bulky cable chain with a [Flexible Flat Cables](https://en.wikipedia.org/wiki/Flexible_flat_cable), while also incorporating the Pyr0-Piezo Z-Probe circuit, fan voltage regulation, motor driver protection diodes, and visual feedback LED's

**Q:** Does this sensor support 3.3v logic controllers?

**A:** Yes, but for Rev.2.x boards, this requires populating a solder bridge (SB1) on the back of the EasyPiezi board
