How to close the low voltage power switch
Low voltage power switches are analog switches designed to operate from a single +2.4 V
to +3.6 V V
low voltage devices.
When switched on, they connect the VGPIO_SPI pin to their output pin, GPIO6 for low
voltage power switch 1 or GPIO7 for low voltage power switch 2, therefore powering the
