Use Battery (Pull P8 high)

max

To boot from the battery on the Expansion Board v3.0 I understand that you have to pull P8 high. I tried this using the following code:

from machine import Pin

pin=Pin('P8',Pin.OUT)
pin.value(1)

print(pin.value())

but that does not seem to have any effect. Do you know what is wrong with the code?

@max You have to pull up P8 physically, because that sensing is done before MicroPython gets active.
