==GPIOs==
=== Description ===
i.MX8M Nano can handle external pins in many different ways and most of them can be configured as GPIOs. When a pin is set as a GPIO, it is possible to read its value, change its direction or change output value directly from the shell.
===Signals ===
The following table describes some GPIOs signals available on J33 WIDE™ connector:

=== Device mapping ===
GPIOs can be used directly on Linux kernel device driver or can be configured on the device tree.
=== Device usage ===
See the [[MITO 8M Nano SOM/DESK-MX8M-L/Pheripherals/GPIOs | GPIOs]] page on the [[MITO 8M Nano SOM/DESK-MX8M-L | DESK-MX8M-L]] Software Manual.
