Uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25 and #24. All other GPIO are unused. Since we had a tiny bit of space, there's 4 spots for optional slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button. See below for the link to get the optional tact switches, they're not included.
This version comes as a mini-kit, with a 2x13 extra-tall female header (to connect the plate to the Pi) and a 2x13 male header that can be used to connect an IDC cable or cobbler from the side.
The photos above also show the optional installed slim tactile buttons. The tactile buttons are not included, but you can pick up a bag of 20 here. Some basic soldering is required to install the headers.
