Description

The Wireless-Tag WT32-ETH01 EVO is a robust, three-in-one communication gateway engineered for IoT system integrators and embedded developers. Built around the Espressif ESP32-C3 RISC-V chip, it delivers reliable 2.4GHz Wi-Fi and Bluetooth Low Energy wireless connectivity alongside a wired 10/100Mbps Ethernet port, providing a fallback or primary network path for critical data transmission.

This module is designed for seamless integration, featuring a complete TCP/IP protocol stack and comprehensive AT command firmware, enabling quick prototyping and production deployment without deep networking expertise. Its hardware design includes a reserved footprint for Power over Ethernet (PoE) components, allowing for clean, single-cable installations in powered device scenarios. The compact form factor and dual mounting options—direct PCB soldering or breadboard-friendly pin headers—make it adaptable for proof-of-concept prototypes and final embedded products alike.

Key Features

  • Integrated ESP32-C3-based gateway with Wi-Fi, BLE, and Ethernet connectivity.
  • Full TCP/IP protocol stack support for immediate network integration.
  • AT command firmware interface for simplified configuration and control.
  • Hardware design预留 Power over Ethernet (PoE) component位置 for streamlined power delivery.
  • Dual mounting compatibility: surface-mount (SMD) or through-hole pin headers.
  • Substantial memory configuration with 16MB Flash and 8MB PSRAM for complex applications.
  • Low-power RISC-V architecture suitable for always-on edge gateways.
  • Compatible with popular development frameworks including Arduino IDE and MicroPython.

Frequently Asked Questions

How do I configure the WT32-ETH01 EVO module for initial network setup?

Connect the module via its UART pins (TX/RX) to a USB-to-serial adapter. Power it with 3.3V, then use a terminal emulator like PuTTY or Arduino Serial Monitor at a baud rate of 115200. Send the 'AT' command to verify communication. Use AT commands like AT+CWMODE to set Wi-Fi mode, AT+CWJAP to join a network, and AT+CIPSTART to establish TCP connections. The module's AT firmware handles the underlying TCP/IP stack, abstracting complex network programming.

Can I program the ESP32-C3 on this module directly using the Arduino IDE?

Yes, you can program the onboard ESP32-C3 chip directly. In the Arduino IDE, install the 'esp32' board package via Boards Manager. Select the 'ESP32-C3 DevModule' as your target. Connect the module's GPIO9 (BOOT) and GPIO8 (RST) pins to ground and release to enter download mode. Use a USB-to-serial programmer connected to the UART0 pins (RX/TX) and 3.3V to upload your sketch. This allows you to bypass the AT firmware and develop custom applications using the full ESP-IDF framework.

What is the purpose of the reserved 'Power of ethernet' position on the PCB?

The reserved position on the PCB is for adding external Power over Ethernet (PoE) circuitry, specifically a PoE PD (Powered Device) module like the TPS2375. This allows the gateway to receive both power and data over a single Ethernet cable, eliminating the need for a separate power supply. This is ideal for industrial installations where devices are mounted in hard-to-reach locations or where centralized, clean power from a PoE switch is preferred for reliability and simplified wiring.
