| 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 LAN-connected master board for interfacing an original A32X, A330, A340 MCDU or 747/757/767 CDU with a flight simulator. It simulates an FMGC/FMC and provides general communication with the connected MCDU. |
