Looks like you typed in the URL on the back of my personal card. Here’s some more about it:

Features

• 802.11b/g/n WiFi + Bluetooth
• 10/100 Ethernet w/ PoE
• USB Type-C w/ 12V PD 3.0
• ATECC508A Secure Element
• User GPIO on standard 2.54mm header

Design

The PSU is a single wide-voltage-input buck converter diode OR’d between the Type-C and PoE inputs. As it lacks isolation, it isn’t technically PoE compliant.

Errata

Ethernet is not functional on cards that use an ESP32-PICO-D4 processor due to lack of chip support. This wasn’t fixed until the most recent run of cards as they’re mostly just to look cool not be functional anyway. I switched to the PICO-D4 at the last minute, and discovered later that one of the clock pins for the MII is shared with flash.
