In no case should the peak amplitude of the command control signal exceed +/- 22 volts. The minimum peak value of the NMRA digital signal needed to provide power to the decoder shall be +/-7 volts measured at the track. Digital Decoders intended for "N" and smaller scales shall be designed to withstand a DC voltage of at least 24 volts as measured at the track. Digital Decoders intended for scales larger than "N" shall be designed to withstand a DC voltage of at least 27 volts as measured at the track.

Because I’ve already bought these and have exceeded my purchase limit for the next few months.
Also, I got 15 or so of these for $15, alongside the fact that I can adjust them. I am confused on the prop mini’s 5v pin. I thought at first that is was an output. Then I forgot it existed and plopped on a 7805. Now I am thinking that I need to nix the 7805 and draw from the mini’s onboard regulator.
Voltage requirements: Regulated 6.5–12 VDC though VIN pin
