Since the IC SO42P is still available for purchase I am interested in the circuit.
Therefore I have made a PCB clone for tracing or for those who want to rebuild this device.
I found some differences between the schematic and the PCB.
Also there is an error on the solder side of the PCB and the parts list.
Everything is marked in red or in red letters in the following pictures. SprintLayout6.0 File: Ready to print PDF-files:
