The Ozeki Matrix is a compact grid of Processing Modules containing microcontrollers. These Processing Modules are conntected to eachother with Connection Modules and the whole grid is placed on a Matrix Board. You can use the Arduino IDE environment to program the Processing Modules for your needs.
Different microcontrollers can control different functions. Your system can be too unreliable if one microcontroller controls too much functions. This is why we designed the Ozeki Matrix with multiple Processing Modules.
