Re: Does the LattePanda's USB-C port support dual-role?

For LP Alpha/Delta, please use the proper subforum.

Re: USB Gadget Mode

All USB ports trace up to Intel CPU/APU's XHCI controller.
Intel's XHCI controller does not support USB Gadget mode nor OTG mode.

Also, please see USB assignment:

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

You'll have to ask LG tech support to see if it supports 15V 3A PD in its PD profile.

Re: Electromagnetic interferences on Alpha/Arduino?

Example of adding a 330uF 12V electrolytic capacitor (do follow the polarity, keep leads reasonably short.)

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.
