Do the CPU Power state pins work?

I'm wondering if I am missing something on these CPU state pins (S0, S3, S4, S5). I tied them to inputs on the arduino and was getting HIGH values all the time, so I tested it with my DMM and I am seeing the same thing. As long as the LPA has power, all four pins always read high. Has anyone seen a ...

Re: Replicating the Power LED?

Great question. I am working with the CPU state pins as well and am always reading high on all of them. Anybody getting a more expected behavior?

Re: L.P. Alpha DC power experiments and observations

vnlevanduoc, I've used the following: https://www.digikey.com/product-detail/en/jst-sales-america-inc/PHR-4/455-1164-ND/608606 https://www.digikey.com/products/en?keywords=455-3083-nd But it looks like this would work as well: https://www.amazon.com/JAGETRADE-Micro-4-Pin-Connector-Cables/dp/B07L67H8...

Re: Input voltage range

Seba, still no confirmation from LattePanda, but check out this post:

I will add that I've been powering mine for a couple of weeks with a 15V power supply, which actually reads 15.3V on my DMM.

Re: suggest a on/off/reset button for lattepanda alpha

Not sure exactly what you're going for, but something like the following might look slick. You could also use the "S0" pin to illuminate the LED.

It may be a bit large though, can you post a pic of your case?

Re: LattePanda Alpha 864 - Bios - Auto-Power-On?

In the meantime, could it be a solution to trigger an Arduino Digital Output port during 5 second, (This port is connected to the SW pins) Must I add a relay for this purpose ? This is a good point, I should have explored this option. SW is asserted by being connected to GND and it sounds like Ardu...
