KiCad schematic and PCB design for a Turing Machine LPG / Mix Expander with various configuration options
This repository provides a KiCad schematic and PCB layout for a variant of the TM-LPG-X expander (https://github.com/morganmcw/TM-LPG-X) and the orignal Turing Machine Vactrol Mix expander (https://github.com/TomWhitwell/TuringMixExpander).
It includes the variation switches of the TM-LPG-X, but can be built using capacitors (LPG), resistors (Mix) or with a pin header to allow switching between LPG or Mix mode via a front panel switch (with the resistors and capacitors mounted on the switch).
