Hardware Assembly

Now that we are familiar with the hardware and sensors on the Weather Carrier Board, it's time to assemble it with
your chosen MicroMod Processor and get it connected to your computer.

With the M.2 MicroMod connector, connecting your processor board is a breeze. Simply match up the key on your
processor's beveled edge connector to the key on the M.2 connector. At a 45° angle, insert the processor board to
the M.2 connector. The processor board will stick up at an angle as seen here:
