I tried to power up the Kali with a DIYinHK LDO reg. but it didn’t work. What is the current draw for the Kali?
I believe the Kali draws around 100mA, so you should have been OK with that reg.
Can you measure the voltage of the reg when it’s connected?
I measured the voltage and all looks good though. Attaching the photos.

Have you had that Kali working with a different supply? If so, does it still work with it?
I can connect it successfully using a powerbank via the barrel connector

Is that white connector making good contact? Can you measure 5v at the barrel connector when your LDO supply is connected?
Gonna do that tomorrow morning. I suspect it might be connection issues. Stay tuned.

Success! I made another connector to power via the barrel instead. So the LDO reg does work. Thanks Jonners for helping all this while. Now I have to figure out why the other connection route did not work.

Glad there was a happy ending!
