06-19-2015 slight update to enlarge the SPI (and other) pins for boards that use the spi (like the arduino touch lcd shields). The AstroPrint Astrobox PCDuino v2 - 3D Print Controller has one thing going for it the PCduino3s does not. Arduino UNO compatible pins! It has Arduino UNO pins as well as Extra 8 GPIO pins that can be accessed from the Lubuntu OS that is currently running your 3d print server. You just need to be able to plug in your UNO Shields or access the individual pins. That's where this case cover comes in. Just remove the original AstroPrint Astrobox PCDuino v2 cover and use this one instead for full access to all the pins. (Running the arduino IDE or other languages to control them are up to you!)
