Frequently Asked Questions

Q: What is the WT32-ETH01 and what makes it different from a standard ESP32 module?

A: The WT32-ETH01 is an ESP32-based embedded module that adds a wired Ethernet interface (via LAN8720A PHY) alongside the standard ESP32 Wi-Fi and Bluetooth capabilities. Unlike standard ESP32 modules that rely solely on wireless connectivity, the WT32-ETH01 allows you to connect your project to a wired LAN network — providing more stable and reliable connectivity for IoT gateways, serial bridges, and embedded applications.

Q: Is the WT32-ETH01 compatible with Arduino IDE or ESP-IDF?

A: Yes. The WT32-ETH01 is fully compatible with the Arduino IDE (using the ESP32 board package), Espressif's official ESP-IDF framework, and MicroPython. There are community-supported board definitions and example sketches available to get you started quickly with both Ethernet and Wi-Fi functionality.

Q: What is the ETH01 Adapter board and do I need it?

A: The ETH01 Adapter board is a breakout/development board designed to make the WT32-ETH01 module easier to work with during prototyping. It exposes the module's pins to standard header connectors, adds USB-to-serial programming capability, and simplifies power delivery. It is highly recommended for development and testing; for final production PCB integration, the standalone WT32-ETH01 module is typically soldered directly.

Q: How many units can I order at once?

A: You can choose from several bundle options at checkout: a single WT32-ETH01 module, a 1-set combo, or ETH01 Adapter boards in quantities of 1, 5, or 10 pieces — making it convenient for both individual makers and small-batch production runs.
