Hi all.
I have wt32 eth01 which has its own psu 5v.
It is hooked upto a SN74HCT245N
The pixels have there Own psu and is hooked it t the other psu… I have a led on the b side off the
SN74HCT245N to show the secound psu is on.
Both psu G are linked.
However the led is lighting up when the secound psu isn’t on and I’m reading two volts on the b side of the SN74HCT245N…
SN74HCT245N specification say it has internal diodes so this doesn’t happen…
Thoughts?

Post a drawing and/or pics of how you have this wired up.
Something doesn’t sound correct…

I’ve found if I remove the eth01 the pixel power led does not illuminate.

Worked out what i had done wrong. I thought one side of the chip need the esp voltage and the other the pixel.
