Shield pin GPIO mapping

Table 2 describes the mapping of GPIO and PWM pin numbers (in Linux) to shield I/O pins. The following details
are included:
•
Shield pin. Digital I/O pin number as per Arduino* Uno* pin numbering scheme.
• GPIO (Linux). The pin number assigned under Linux.
•
Muxed functions. Other signals available on this shield pin, as they appear on the schematic.

1 Some additional functions are available on certain SoC pins, such as I2S and UART flow control, but they are not currently
supported by the Arduino library. However, it may be possible to use these from Linux.
2 Depends on PWM swizzler. The SoC offers only four PWM pins. A jumper pin matrix labeled "PWM swizzler" on the baseboard
allows these four pins to be connected to any subset of the six shield-header pins normally used for PWM. From the factory,
IO3, IO5, IO6, and IO9 will be connected to the four available SoC PWM pins as described above. You can manually alter
these to connect IO10 or IO11.
