Wireless-tag WT32-ETH01 PRO RJ45 Ethernet module based on ESP32-S3 16M Flash Communication ESP32 development board with POE Embedded Serial Port for IoT Gateway

We're the original factory to R&D WT32-ETH01 PRO. Please buy the AUTHENTIC product from us! Welcome to inquiry us to get more details!

WT32-ETH01 PRO is an Ethernet development board based on the ESP32‑S3. It integrates a DM9051 10M/100M Ethernet MAC chip and provides an RJ45 Ethernet port and two 19‑pin expansion connectors. It is suitable for IoT terminals, industrial control devices, network gateways, and development verification scenarios that require stable wired network connectivity.

The development board exposes common ESP32‑S3 signals such as IO, USB, UART, reset, power, and net‑work status signals, making it convenient for peripheral expansion, functional debugging, and secondary development. The expansion connectors use a 2.54mm through‑hole / castellated‑hole compatible form factor, making them suitable for pin headers, female headers, carrier boards, or custom baseboard integra‑tion.
