| CockpitSquare overview | A CD74HC4067-based breakout board that multiplexes or demultiplexes up to 16 bidirectional analog or digital channels. It is intended for DIY electronics projects requiring sensor, TTL serial, I2C, SPI, or similar signal routing. | A set of non-assembled printed circuit boards for building backlighting and gauge-stepper-motor interfaces for a Boeing 737 forward overhead panel. The boards use specified SMD component footprints, include MAX7219-based display integration, and are intended for DIY assembly. |
