Custom Raspberry Pi Add-on board used for launching the Galactic Aztec rocket to interface with the Galactic Aztec Igniter Connector. The board was designed to be stackable with other add-on boards via the designated pin configuration.
Custom EagleCAD parts on this board can be found in the SDSU Rocket Eagle Libraries.
The igniter and break wires that ran from the add-on board to the rocket's igniter were CAT6 cables that ran thru RJ45 couplers and followed the following T-568B wiring configurations:
