What is SIMINPUT

We make button boxes that are modular, affordable, configurable in your browser, and easy to assemble yourself, with extremely high customizability. The whole hardware design is open source, from the firmware to the CAD and the PCB. You can order a box as a kit or as a fully assembled unit.

Details about mounting, modules & electronics

Open source freedom

Design a new module, wire in your own parts, or change how the box behaves. The hardware design is open and documented.

Backlit custom labels

Set the text on the backlit labels so you never forget what a control does.

Expandable and adaptable

Replace a label or swap a module down the line to keep your box useful forever.
