First look at the driver I/O board for projects like pinball and mechanical games. It works like Master Blaster from Mad Max. You connect your controller, either by piggybacking or by dupont leads. The controller is the Master, the AVON is the Blaster.
If you choose piggybacking, this board is designed to use the Ultimarc U-HID, which will fit the two sockets.
What does the board do:
- General board, will drive coils, lamps etc.
- Voltages from 5-50V.
- 19 MOSFET outputs (up to 20A per channel)
- 27 inputs (only for piggybacking, otherwise redundant)
- LED for each channel to see if the controller is outputting signal.
- Back-voltage protection*
- Pull-down for floating pins on the controller
- Only 3.96mm (0.156″) connectors
*Protection is never 100%!
