Product Description

The WT32-ETH01 serves as an embedded serial port to Ethernet module based on the ESP32 series. The module integrates an optimized TCP/IP protocol stack, allowing users to quickly implement TCP/IP networking functions of embedded devices, thus reducing development time and cost. The module can be directly soldered onto a mainboard or used on a breadboard, allowing the application in different scenarios. In addition, the module is compatible with half-pad and through-hole connectors.

The ESP32 series of ICs by Espressif Systems are SoCs (System on a Chip) that integrate 2.4GHz Wi-Fi and Bluetooth dual-mode, with ultra-high radio frequency performance, stability, versatility, reliability, and ultra-low power consumption.

The module ships with firmware that uses AT commands to control the communication, but you can easily change that, as you can on every ESP32, and run Arduino code or MicroPython.

WT32-ETH01 Main Features


  • Dual-core Xtensa®32-bit LX6 MCU. Integrated SPI flash 3.32Mbit\ SRAM 520KB
  • TCP Server, TCP Client, UDP Server, UDP Client working mode.
  • Four data ports for serial communication, WiFi. Ethernet and Bluetooth to be combined in pairs, and the data is transparently transmitted.
  • Connects to the network through wired network or wifi to upgrade the firmware.
  • WiFi to connect to the Internet or LAN through a router, establish a TCP/UDP connection, and access the user's designated server.
  • Wired network access.
  • Supports user secondary development.
  • Industrial grade operating temperature range: -40-+85 C.
  • Serial port baud rate: 80-5000000.
  • Network protocol: IPv4, TCP/UDP.
  • Software encryption: AES/RSA/ECC/SHA
