reduce power consumption

[Agoff]

Hi,

we've been trying to reduce power consumption do I able to connect unused pins to GND directly?

Trace 1,2,3,4 do I able to connect to the GND?

Thanks, in advance.

"The default (from reset) state of all GPIO is as a disconnected input. Unless you’ve previously configured them to something else, you can leave unused pins in their default state and physically disconnected to draw no current."
