Anne Pro 2 support?

[jedahan]

I know it was just announced, but wondering if we could have a tracking issue for what chipset it is, etc.

[hdhoang]

sure thing! Such info would fit nicely in the book, even if we don't have any code for it. I'll be on the look out for them

[jedahan]

Okay I ordered one, should be here in a few days, will see what the differences are

[therealprof]

I also ordered one last Saturday from China. Although it was on backorder very much to my surprise it already arrived today in Germany...

[jedahan]

Got mine in too, what commands would be helpful? lspci? lsusb? opening it up and taking pictures?

[ah-]

Exciting! The latter, close up pictures of the chips so we can see if they're the same.

The included images were posted in the Discord by Flashquark, the chip seems to be a HT32F52342
Higher quality images of the PCB would be much appreciated though!

[jedahan]

hmm these aren't as good as the ones you already have

[jedahan]

It does look like there is something like DFU mode if you hold esc while plugging in the usb c. Not sure if we can inspect that, maybe with a facedancer or something.

[therealprof]

@MvEerd Sure thing, anything in particular you'd like to see?

[ah-]

Got a pic of the bluetooth chip? It's under the little metal shield on the left of the board.

[therealprof]

Hm, not sure I want to remove the can... There's so much plastic on the board and I'm not not I can protect that...

[therealprof]

Lol, the can is only hold in place by tabs, it's a CC2541. Need a photo? I'd have to fire up the microscope then, it's barely imageable using a camera.

[ah-]

Cool, that's all I wanted to know :)

CC2541 is the same chip as on the previous Anne.

Here you go: It's as high-res as I can do right now and best quality GH would allow me to upload. ;)
