Description

The WT32-ETH01 Serial to Ethernet Gateway Module is a robust networking solution built around the Espressif ESP32 chipset. It functions as a bridge, converting serial data from industrial sensors, controllers, or legacy equipment into Ethernet packets for seamless integration into modern IP-based networks. The module’s integrated Wi-Fi and Bluetooth provide additional wireless connectivity options, enabling hybrid wired/wireless deployment scenarios.

Engineered for reliability, it operates across an extended industrial temperature range and features a hardened TCP/IP stack with support for essential security protocols. Its compact form factor and flexible mounting options make it suitable for embedding directly into end-user products or industrial control panels, significantly reducing development time for IoT system integrators and hardware developers.

Frequently Asked Questions

How do I configure the WT32-ETH01 for serial-to-Ethernet conversion?

Configuration is typically done via AT commands over a UART serial connection. Connect the module's TX/RX pins to a USB-to-serial adapter, power it with 3.3V or 5V, and use a terminal emulator (e.g., PuTTY) at a common baud rate like 115200. Issue commands to set the module's operation mode (TCP Server/Client, UDP), local IP address, target server IP/port, and serial baud rate to match your connected device. The exact command set should be referenced from the manufacturer's documentation.

Can I program the ESP32 on the WT32-ETH01 using the Arduino IDE?

Yes, the onboard ESP32 can be programmed via the Arduino IDE, ESP-IDF, or MicroPython. You will need to access the module's programming pins (typically GPIO0 and EN/RST) to enter bootloader mode. Connect a USB-to-serial programmer to the main UART pins (TX/RX) and ground. Hold GPIO0 low while powering on or toggling the EN pin to enter download mode, then upload your sketch. Note that programming may override the factory AT firmware, so back it up if needed.

What is the power consumption and sleep current of the WT32-ETH01 module?

While specific sleep currents aren't provided, the ESP32 chipset supports deep sleep modes which can reduce current to microamps. Active current draw depends on Wi-Fi/Ethernet activity and CPU load. For power-sensitive applications, utilize the ESP32's deep sleep functions via GPIO or timer wake-ups in your firmware. Ensure your 3.3V or 5V power supply can deliver sufficient current (likely several hundred milliamps) during RF transmission and peak processing.
