Can PSRAM be used on Pimoroni Pico Plus 2W?

I have used PSRAM with a Pimoroni Pico Plus 2 on pin GP47 with no problem. Now I’d like to try the 2W instead but it gives me invalid GPIO when I try OPTION PSRAM PIN GP47.

Is there a way to use the PSRAM on the 2W?

I hit the same problem.

Webmite does not support gp47 with PSRAM but Picomite does, so you can have wifi or PSRAM, but not both.

According to Peter on TheBackShed, Webmite does not support the Pimoroni Pico Plus 2W. (And presumably never will.)

His response is on the next page from here:

Webmite does work on the Pico Plus 2W, though I just played around with it so I can’t say how stable it is. The wifi works and I was able to set the time with web ntp.

Oh wow. Everything I had read on TheBackShed said it didn’t work. I don’t have one to test. Sounded like the CPUSPEED had to be set rather low too, supposedly due to stability issues (even without using WiFi).

Yes, I didn’t try to change CPUSPEED at all.

I may have been too encouraging to say it works. Your mileage will definitely vary with this.

You can through get up and running and determine your own confidence.

Yes. I can’t go over 200000 on the Pimoroni, whereas on the official Pico, I can run at 252000.
