Hello!

I ordered HDMI/USB reference design assembled from JCLPCB.
Arrived, seems good quality.
One question I have:
There are 3 small hole from the backside I have to solder.
Two of them for programming connector and one of them for GP23 it seems.
But if I place the Pico2W right on the PCB I can only solder the two holes gor programming.
The third hole is not located in the right place seems.
Is it necessary to solder it also?
Is it a PCB problem? Design problem?

Thanks!

The board is designed for the Pico2 not the Pico2W

You won't have access to GP23 on the edge connector, otherwise it should be OK

Or is there any special way to use Pico2W with this PCB?

If you use the webmite fw then hdmi won't work. This board is designed for the HDMIUSB firmware with a Pico2
