Arrange the two NeoPixel rings face down on your work surface. It can help to use tape, sticky side up, on your desk to help keep the rings aligned while you solder.
Make small pieces of solid-core wire shaped like staples to connect 5V, GND, and data between the two pixel rings according to the circuit diagram.
Solder longer wires as shown to the extra 5V and GND on the outer ring, as well as data input.
Place the GPS/FLORA circuit in the center and solder these longer wires to VBATT, D12, and GND on FLORA according to the circuit diagram.
Test the NeoPixel rings by downloading the NeoPixel code library and running one of the test Arduino sketches provided.
