Using MPP on stwlc38

[Jvan .23]

Is it possible to use a Qi2 rx coil with magnetic array on a stwlc38 design?

The goal is to use a Qi2 charger and reap the benefits of magnetic alignment and 15W charging while still being on the Qi1.3 standard of the stwlc38.

Dear Customer

STWLC38 doesn't support Qi 2.0 spec, but Qi2 rx coil can be used.
So you can use Qi2 rx coil and magnetic to do 15W QI 1.3 power transfer.

We plan to release MPP stamp module, do you consider it?

Interesting. If we would have to start over the project (so the layout was not done already) we would definitely consider it, also depends on pricing.
