The MobiFlight Multiplexer Breakout Board is a breakout board for easier use of the 74HC4067 multiplexer.
On the top side, The board uses XH JST connectors for the individual inputs. On the back, you can add up to two 74HC4067 modules (https://shop.mobiflight.com/product/multiplexer).
On the bottom side, you plug in the 74HC4067 modules. Version 1.2 now shows information about the orientation and all important pins are labeled. You can daisy chain the boards.
For more information on how to configure the board with MobiFlight, check out the MobiFlight Connector documentation.

As one can see on the picture, the 74HC4067 are mounted with the silkscreen facing up. Due to the asymmetric connectors, the orientation cannot be confused.
This information will be added soon.
