IOB-Inputs

Fork project on GitHub

IOB interface provides 1x IO4 port with 4x Input i/o lines.

  • A 1k series resistor protects the processing electronics from shorts to Vcc or GND * Schottkey diodes and a 1kHZ low pass filter protect the inputs from noise/transients/+12v * Updated to new IOB design
