With these shield cards you can use Hispapanels printed circuit boards with Arduino Mega control cards and Mobiflight software.
This is a shield card to be connected on an Arduino board. On the other side these cards connect with the PCBs for B737 forward overhead panels. This way the forward overhead panel can be controlled using Arduino + Mobiflight.
This PCB is a patch panel to connect our PCBs for B737 transponder radio panel to an Arduino board. Then you can use Mobiflight software to control this panel. Trim, Stab trim and printer panels are connected to this card too.
