| 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 small shift-register output-expander board for increasing a microcontroller’s available outputs, including LED outputs. It uses four serially interfaced 8-bit shift registers, supports cascading, and is intended for integration with MobiFlight. |
