Re: Electromagnetic interferences on Alpha/Arduino?

Not sure it's EMI related or it's just insufficient decoupling.

I'd recommend place a low ESR 470uF 12V tantalum capacitor as well as
a low ESR 0.1uF 25V ceramic capacitor in between the
Arduino 5V and Gnd edge connector.
(Making sure the leads are as short as possible.)

Re: A question about usage of the USB type c on delta 432

You can also use a Blitzwolf BW-TH5 as a combo:
USB-C power pass-through (supplying power to LP Delta) <-- at least 15V 3A mode,
as well as
3-port USB-3.0 hub, HDMI output, and SD card reader.

Re: A question about usage of the USB type c on delta 432

I've tested:
1. supplying 15V 3A power directly from USB-C PD mode
2. LP Delta when powered by 4-pin DC_in, I can activate LP Delta's USB-C as PD source mode, supplying 5V as output

What else you need me to test it for you?

Re: Can I power LattePanda Alpha 864s with LG 32UD99 monitor??

Please check if LG 32UD99 monitor can support USB-C 15V 3A PD mode.
If yes, in theory, it could work.

My opinion:
Sorry, USB-C is such a not-so-stable standard. It is works, it's a blessing.

Re: 15.6" / 17.3" eDP Displays for LattePanda Alpha!?

Wow. That's a surprise.
The eDP panel I have works for both models.
Since there is no detailed info on Alpha vs. Delta, I am afraid that I could not help on this.

Re: 15.6" / 17.3" eDP Displays for LattePanda Alpha!?

Lattepanda delta 30pin eDP problem https://youtu.be/N6t2eHJSev8 That's a telltale sign that LP Delta is having trouble interfacing with your eDP panel. I have no means to help troubleshooting all kinds of eDP panel issues. They are not necessarily universally compatible. It may just a simple issue ...

Re: Latte Panda Alpha Not Powering Up Blue LED blinks

Your symptom seems to me quite unusual (not completely dead....)
I'd say next step is to contact LP Tech Support and see what they say.

Thanks!

Re: Connect Display

LattePanda classic's (v.1) display is MIPI-DSI type, while LP Alpha/Delta is the more modern eDP type.
Apples and oranges.
