27    Panasonic's reduced Arduino header is based on the Arduino UNO layout
28    and provides four different headers. The main difference is that some
29    pins are not available due to the lack of pins on the Panasonic module.
30    These unconnected pins are labeled "NC" in the mapping above.
31
32    So:
33
34    1. Power Supply header exactly, like on Arduino UNO layout.
35
36    2. Analog Input header, like on Arduino UNO layout, but A4 and A5 are
37    not connected.
38
39    3. 8-pin header (opposite Analog Input).  Digital input signals, like on
40    Arduino UNO layout, labeled from D0 at the bottom to D7 at the top, but D6
41    and D7 are not connected.
42
43    4. 10-pin header (opposite Power Supply). Digital input signals, like on
44    Arduino UNO layout, labeled from D8 at the bottom through D15 at the top,
45    but D8 and D9 are not connected.
