Editing Wiring

=== Wire reference ===

For wiring, use 20-28 AWG. 18 can be too stiff while 30 is too fragile. 24-26 AWG works fine in most cases. The Grounds and VCC wires may ofcourse be thicker than the signal wires. Keep wires short, up to ~20cm max (longer gives errors). The shorter the better : 15cm and shorter mostly works fine with AWG26 on SPI.

Use [http://en.wikipedia.org/wiki/Calipers%20caliper caliper] to measure unknown/unmarked wires and compare with table/listing.
