HP100

It is the motherboard of the Helvest Flex system. It controls the modules installed on board, and can perform many different functions based on them.

The “layout” type modules interact with the layout (they operate switches, signals and accessories, detect the presence of trains, control the behaviour of accessories).
The “net” type modules communicate with the control system (such as the digital control unit, the PC, the control bus of the layout).

It handles up to two different layout modules and one net module.

The modules are “plug and play”: the board recognizes the installed ones and adapts automatically its behaviour.
