Claim 9:
10. The modular system of claim 7 wherein the expansion signal support system further comprises:
a plurality of driver circuits, comprising:
an optocoupler that receives a shift register input;
a configurable drive voltage configured to receive one or more of a native voltage from the earth-moving vehicle and a power supply of the modular system;
an amplifier output connected to an NMOS amplifier;
a MOSFET drain connected to a jumper to allow for selection of either the native voltage from the earth-moving vehicle or the power supply of the modular system; and
voltage transient protection on the jumper;

two low-power microcontrollers with a signal interconnect between them; and
one or more status indicators to indicate board state.
