All the GPIO signals are 0-3.3V level.

Device mapping[edit | edit source]

GPIOs are mapped into banks each of which contains 32 pins. They are named as GPIO<bank>_IO<pin>

Each pin can be addressed with an incremental number, calculated as follows: GPIO = 32 x (<bank> - 1) + <pin>

Device usage[edit | edit source]

Under Linux the GPIOs can be manipulated su sysfs export or with the gpio tools.
