This is an old revision of the document!

Ever need to test a switch assembly or sensor that will eventually plug into a RoboRIO DIO port or motor-controller limit switch port? Or just provide power to somthing with the FRC-standard 3 pin connector?

Version One: Input only FakeRio

Steve uses a perfboard version of this to test and demo various FRC electrical bits.

On this board are:

12VDC Input with protection against reverse polarity and overload
generation of 5 volts using a classic linear regulator
an LED that indicates that the 5v supply is OK
two, three, or more copies of the basic DIO connector circuit
- each with an LED to indicate “low” status on the signal pin
