We have been searching some application references in which WIZnet solution is applied, and found your project “PoE LAN Intercom doorbell sound module(https://www.dxsdata.com/2015/03/poe-lan-intercom-doorbell-sound-module)” using Ethernet Shield. In the Ethernet Shield, WIZnet’s W5100 chip is embedded. Your development looks very cool & smart.

Recently we opened WIZnet Museum (http://wiznetmuseum.com) that includes a academic-purposed collection of open projects, tutorials, articles and etc from our global customers.
As long as we have your permission, we would like to introduce your project on this website.

Hopefully, we would like to keep in touch with you for the further friendship.
Thank you very much.

Regards,
Eric.
