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

case 1: do i just only fill quantity of pcb in Assembly Service Menu ? ex. i order 10 pcs pcb assembly service but how about in PCB Specification Selection Menu ? i saw there's 5 quantity, do i need change quantity too ? same with assembly service ? case 2: if i order 10 pcs pcb but order 5 pcs assembly service , so i get 5 fully assembled and 5 pcb only right ? many thanks . again sorry for my bad english
After pass review and finish the quotation,then you could place order
It should be fine on the Uno with its 5V inputs being able to read the op amp trigger outputs
I have just added the BOM to the shared project.
Thank you so much! I am assembling this PCB today. I am hoping I do soldering well and see this working like you did. God bless you!
