WBC86TX, WLC38RX, STSW-WPSTUDIO Datasheets and Software

[SRiesi]

We bought the following evaluation boards to test a wireless charging concept:
STEVAL-WBC86TX
STEVAL-WLC38RX

Now it seems that the datasheets of the evaluation boards and also from the chips that they use got pulled from the website. The control software STSW-WPSTUDIO also is nowhere to be found.

Is there some way to get all these files still or are they just gone for good due to some restrictions...?

Dear customer.
The support for mass market has been restricted, and documentation has been retrieved from the website.

I can provide you the GUI on demand, please open a case on st.com (https://www.st.com/content/st_com/en/support/support-home.html#), you ticket should be re-directed to me and I will be able to support you directly.

[SRiesi]

Thanks for the fast reply! I opened case 00238225.

Hi @SRiesi I'm sorry for chiming in, but I opened the case 00238307 about the software, and I was told "It may be available with some quantity qualifications with a direct ST contact. Usually, this type of support requires a sales volume of about $1 million/year."

I can't believe my eyes; have you received a similar response?

[Didier HERROUIN]

Dear customer,

I just answered to your case, providing the documentation you miss.

We did not set a threshold to 1M$ minimum, but it is true that support to mass market project may be reduced.

It depends also on your constraints (for instance, if you want to design your own coils, it becomes much more complex).

For what's worth, we haven't received any software in 00238307. We've been advised "to ask a question in our very active community forums" :clown_face:

Yup. Welcome to ST. $1,000,000 is ridiculous.

That's 333,333 tx or rx chips in a single year. Like who does that kind of volume? Not many.
