VM141 Question

Modules Home Projects

I am looking at this module for a home project. I may have to make a modification to it to work for my application. However I have been unable to locate a schematic for this module. Is there one available and does it use the 555 timer chip for its timing?

Thanks

No, it uses a PIC microcontroller.
