Wiring the Cabinet I/O board in a FAST Neuron-controlled pinball machine

Wiring, high voltage, and electricity can be dangerous. Read this first!

The voltages and electricity discussed here can be dangerous and could cause property loss or death. It is your responsibility to ensure you are comfortable doing the things discussed here. Furthermore your local jurisdiction may have regulations or rules which differ from what we discuss here, including wiring colors, standards, techniques, etc. Seek professional guidance from someone local to you if you are unsure of anything you're doing here. Also there could be errors, omissions, or typos here. Use this content at your own risk.

This guide is for FAST Neuron-powered machines only

This wiring guide is for pinball machines powered by a FAST Neuron Controller. If you have a FAST Nano Controller, please see the Nano wiring guide.

The Neuron wiring guides are incomplete works-in-progress

NOVEMBER 2022 UPDATE: We are in the process of creating & updating the wiring guides for FAST Pinball Neuron-based systems. We are publishing our work-in-progress docs to get as much information out as soon as possible. If you have questions or want clarifications, please reach out via email to me (Brian), via

Since we are just now in the process of creating the wiring guides for the upcoming general availability of the FAST Neuron Controller, this guide is not yet complete.

But here's our brain-dump / notes of what will be included in this document, as well as some high level thoughts about it.

  • At the surface, this is essentially a 2408 I/O board
  • Has lots of convenience tweaks for use in a cabinet
  • Designed to be installed in the front left corner
  • Header for coin door
  • Neuron systems have no restrictions for which switches and driver are connected to which boards, so you can have your flipper buttons connected to this board and the flipper coils connected to a different I/O board under the playfield
  • Low current drivers are used for lighting, flashing start button, coin reject LEDs, etc.
  • High current FET is designed to be used for the knocker.
  • Do not use this board for a shaker motor? Why? Because a shaker needs extra protection and control, and we have a dedicated board for that with everything built it.
  • If you don't use the knocker, then you do not need 48-volts in the cabinet.
