WLC poller/listener development boards or and app notes

[Val]

I am lost and confused between the wireless charging topic when it comes to development boards. Which ones should we order in order to test the working principle of the wireless up to 1W charging?

Is ST25R3911B-DISCO the one to use as the WLC-Poller? Or is there something better?

As for WLC-Listener development boards, we are unable to find any suitable options, all of them only mention energy harvesting, not charging.

 

At the same time, do you have app notes on both poller and listener blocks? We would be interested in building our own system as soon as possible.

When can evalutionsboard become available? The topic has been discussed for 2-3 years but nothing has happened in this direction.
It would be nice to know what the roadmap for NFC WLC looks like.

 

Thanks
