Imagine all of the things you can do with a NeoMatrix Mk I, the Interface of Infinite Possibilities! From puzzle box to step sequencer, from NeoPixel programmer to crypto generator, from TV prop to phone phreaking device, the choices are endless. Think of it as a platform for experimentation and interface design.

At the core of the NeoMatrix Mk I is a NeoSegment RGB LED character display, driven by an Adafruit Metro with a phone pad 3x4 button matrix and two knobs as inputs. It also has a built in piezo buzzer for sound indicators.

The NeoMatrix Mk I has a lighted pushbutton that can be used for any purpose you like, and an externally accessible USB port for data and power. You could also convert it to run from battery power with a USB battery pack or a LiPo battery and PowerBoost.
