Sig7Seg - A Signalex 7 Segment display controller

Date: 2017-10-07

Another Signalex "402L" electro-mechanical seven segment display controller. These 4 displays are each controlled by an "Sig7Seg-i2c" board which is open sourced. This design uses the popular MCP23017 which can easily be controlled by an Arduino, Raspbery Pi, or other micro-controller using 3.3 or 5 volts. I've also designed a version of the board as a Particle Photon Shield so everything can run from the same 12 volt power supply and the voltage will get converted.
