Description
Piezo Drum Trigger Signal Conditioner Interface (4-ch)
When piezo transducers are mechanically struck, they generate voltage spikes that can vary in voltage level, polarity, and active duration. The voltages can be a few volts or many tens of volts.
This pcb provides an interface between piezo elements and a microcontroller input (analog or digital). It limits the voltages to safe levels, filters them, and provides a more consistent level-sensitive output as the device is struck with varying intensity.
This pcb provides a 4 channel signal conditioner, allowing piezo elements to be used in a drum sample player on Teensy 4.1
