12.13 How to enable the 3.3V and 5V power supply on the
Expansion connector
3.3V and 5V are OFF by default and are controlled driving specific GPIO's.
To control the 3.3V, enter the following commands:
#turn on 3.3V
gpio_utility gpio71 1
#turn off 3.3V
gpio_utility gpio71 0
To control the 5V, enter the following commands:
#turn on 5V
gpio_utility gpio70 1
#turn off 5V
gpio_utility gpio70 0
While the default kernel DTB allows access to these power control pins, depending on the device
tree used, control of these power supplies is handled by the kernel and therefore it may not be
possible to control them from user space.
