Note! This board ships without the PiZiGate + (Zigbee PCB antenna) as standard so you would need to add that option to use it:

ZiGate radio and this should work out-of-the-box with Home Assistant’s ZHA integration via the zigpy-zigate radio library for zigpy

According to fairecasoimeme it should also be compatible with ESPHome using esphome-zbbridge as alternative firmware:

Board is apparently sized to fit the enclosure case made for Raspberry Pi 4

Also, since the ESP32 in this essentially only provide a serial-to-ip proxy server functionality this gateway/bridge should in theory also work with other Zigbee HATs/shields for Raspberry Pi, like the Elelabs shield, RaspBee HAT by Dresden Elektronik, and ZigStar shield, or others too, such as for example:

Guess that it should also work with Z-Wave shields and others using GPIO serial interface.

Note that it is usually required to disable Wi-Fi on ESP32 in order to use the wired Ethernet function. Also, it is recommended to disable WiFi regardless so that it does not interfere with Zigbee signals.

PS: Obviously, the ESP32 should also be able to act as a Bluetooth Low Energy (BLE) gateway too.
