Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Is the pinout the same as with the original?

Looks like a slightly enhanced copy of the original. Just not castellated. Me-likey!

I have ordered a couple so as soon as Aliexpress can deliver....

Pinout is *NOT* the same. Be careful.
Just a quick look reveals:

3V3EN is replaced by a GND.
pin 30 is GP26, not RUN
pin 31 is GP27, not GP26
pin 32 is GP28, not GP27
pin 34 is GP29, not GP28
pin 36 is GP24, not 3V3
pin 37 is 3V3, not 3V3EN

If you plug this into a lot of boards it won't work - you'll be putting 3V3 onto the GP24 input. No boards will put 3V3 on the 3V3EN input by default.

Likewise, don't design around this then expect to be able to substitute it with a Pico.

I suspect there's an on-board linear regulator, you can't disable it anyway. What the current capability will be like I've no idea - it's unlikely to be much - and whether you could power this via the 3V3 pin without damage I've no idea either.

Different Pinout = No interest in buying. Thanks for the info!
