From reading the posts it seems to be impossible to charge the lattepanda alpha through usb C, and power an external display at the same time. (Please correct me if im wrong). So the only (good) way to solve this is to wait for a lattepanda alpha with two usb c connectors. Again, correct me if i'm wrong. Does anyone know if this is on the roadmap?

Hi assel, what's display do you use? How about its power consumption? the USB C can only power up LattePanda. Please describe your project design in detail and we can check if it can work.
Enjoy Tinkering with LattePanda ! :lol:

Thanks for the reply! I would like to power something like the ASUS ZenScreen MB16ACM
The thing is, I will mostly just connect it to powered monitors, but sometimes it could be nice to use it as a laptop replacement were I power it with a high end usb c power bank, and feed the display at the same time

Hi assel,
Another way of thinking is to let the USB-C interface on the Lattepanda output video signal, but also let the screen power the LattePanda. USB-C interface allows the seamless connectivity of data, PD power supply, and 4K video output. You can find a USB-C display which can power LattePanda. Here is the screen for your reference.

@ OP
If you place your question in LP Alpha/Delta related subforum, you may get more appropriate responses.

I have been using the original 45W USB-C PD power adpter to
supply power to both the LP Alpha (or Delta) and a
10.1" (or 13") eDP monitor thru the 30-pin flex cable wthout problems.
