CV in controls the clock oscillilator an external CV-to-pulse-rate module? Is this even useful? - Seven-segment display. Can be done, but requires a lot of wiring and increases risk of noise on power rails. Things best left to external modules: CV-controlled CV offset module - add a switch of some that get squished or have excessive padding. ``` cd /path/to/ttrss/ git clone git@github.com:holmesrichards/precadsr.git New KiCad version; non Al panel Gerbers *~ New KiCad version; non Al panel Gerbers # Netlist files (exported from Pcbnew # Exported BOM files *.xml *.csv # KiCad backups folders *-backups # Compressed.
