How about a new repository for a KiCAD project to copy the SM1000 support circuitry, e.g., A/D, D/A, PTT, LED's, etc, onto a RPi4 HAT. Maybe include a +12 VDC connector to power everything.
The circuits are tested already, so bada-bing... _______________________________________________ Freetel-codec2 mailing list Freetel-codec2@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freetel-codec2
