Gold-plated magnets and spring-loaded connector pins ensure a secure connection. Multiple Grid modules connect to each other through these pins, modularity is built upon this capability. Power and data flows freely between modules of the system over this connection.
Each module has a USB-C connector, but even one of them is able to provides ample power for your whole control surface. There is no dedicated 'brain' module, any one connected module is able to function fully by itself, no further modules required. By adding more and more modules, you can expand your control surface up-to 10 modules connected by a single USB-C cable.
Grid modules are uniform, four-by-four inch blocks. They are designed to be customizable as a system, so they can fit any kind of desktop layout the user prefers.
