I tried using an TPL5110 Timer breakout along with my pico in order to make it a really low power device for battery usage.
However it seems that when the pico receives power all GPIO goes high (I measured 50mV) for a very brief moment. This causes the TPL5110 to cut the power to the pico as it thinks that the pico is sending it a "done signal" on the done pin.
Is there a way around this? Could it be avoided by using C instead of micropython? Or perhaps do something funny in boot.py?
One solution seems to be to use capacitors but I'm currently out of capacitors...
