Looping ADSR front view

This Module is build around the LOOPENV 1B Pic chip from Electric Druid.I have bought the pic chip and added some protection and level shifting circuitry around it. For details of that chip please refer to the original documentation from Electric Druid.

The documentation for download can be found in my website.

Nothing special here. Just some standard input protection for the pic chip and a filter for the PWM signal to generate the output voltage.
