TM5 Gate/Trigger Input
this is one essential part for my triggermatrix5
* Levelshift from 5V to the for the MCU required 3V, with a Resistor Divider
* Overvoltage Protectect with TVS-Diodes
* Preamp-Section
5V, 3V or Pre-Amped input - can be set vie Jumpers and Potentiometers, the PCB itself should be mounted on the Groundplate off the housing, the housing should have a service-plate to access this Settings!:
8 Channels, are managed here, so in order to have 16channels, you need 2 off this PCBs
if you dont want a Preamp, then dont stuff the Preamp-section > this will make this PCB a lot off cheaper!

Follwing list is for reference, and debugging only, no need to order them! all the parts are already soldered on the PCB!
