From the project
CDV (Community Digital Version) of the switching power supply ADB-3020
The ADB-3020 is an excellent switching power supply designed by an Italian team and licensed under Creative Commons (the original project and credits are in the adb2030Original subfolder).
The CDV (Community Digital Version) fork is intended to start with version 2.1 (last published on the fork date) and then extend it with digital functions via MCU. The project started with the creation of Eagle .sch because the original authors have decided not to release the productions files. Now Eagle file is deprecated, the project is ported on KiCAD.
