WT32-ETH01 ESP32 Ethernet WiFi Bluetooth UART Serial Gateway IoT Module

Description �� WT32-ETH01 ESP32 Ethernet WiFi Bluetooth Serial Gateway Module | AuscomTech The WT32-ETH01 is a compact and industrial-ready embedded serial networking gateway based on the ESP32 platform, combining Ethernet, Wi-Fi, and Bluetooth connectivity in a single module. Designed for serial-to-network communication, this module enables embedded devices, sensors, PLCs, and controllers to connect seamlessly to LAN, Wi-Fi networks, and Bluetooth links using transparent data transmission modes. It is well suited to IoT gateways, industrial automation, smart devices, and network-enabled embedded systems where reliability and protocol flexibility are required. ⭐ Key Features Triple Network Connectivity – Ethernet (10/100 Mbps), 2.4 GHz Wi-Fi, and Bluetooth 4.2 (BLE) Serial-to-Network Transparent Transmission – Direct UART data forwarding over Ethernet, Wi-Fi, or Bluetooth ESP32-Based Architecture (ESP32-S1 marking) – High RF performance, stability, and low power consumption Integrated RJ45 Ethernet Interface – Reliable wired networking for industrial environments Multiple Network Modes – TCP Server, TCP Client, UDP Server, UDP Client IP Configuration Options – Static IP or DHCP Secure Communication – WPA / WPA2 / WPA2-Enterprise support Flexible Mounting Options – Half-hole pads and through-hole headers for PCB or breadboard use OTA Firmware Upgrade – Remote firmware updates via Ethernet or Wi-Fi �� Technical Specifications Core System Microcontroller: ESP32 series Flash Memory: 32 Mbit CPU Architecture: Dual-core ESP32 RF Band: 2.4 GHz ISM Networking Ethernet: 10/100 Mbps Wi-Fi: IEEE 802.11 b/g/n (Station / SoftAP / STA AP / P2P) Bluetooth: Bluetooth 4.2 BLE Network Protocols: IPv4, TCP, UDP Serial Interface UART transparent transmission Baud rate range: 80 – 5,000,000 bps Default baud rate: 115200 Power Supply voltage: 5 V or 3.3 V (select one only) Average operating current: ~80 mA Recommended peak supply current: ≥500 mA Environmental Operating temperature: -40 °C to 85 °C Ambient conditions: Industrial environment Physical Dimensions: 58.2 × 25.5 mm Weight: ~15.3 g �� Pin & Interface Highlights UART TX / RX RS485 enable pin Multiple GPIO pins for user applications Ethernet LINK status indicator pin Dedicated enable, configuration, and boot pins Note: IO36, IO35, and IO39 are input-only pins. �� Typical Applications Serial-to-Ethernet gateways IoT edge gateways PLC and industrial controller networking Smart home controllers Energy monitoring systems Environmental sensing and data logging Remote data acquisition Embedded communication systems ⚠️ Important Notes Ethernet, Wi-Fi, and Bluetooth operation is configurable via AT commands Only one power input (5 V or 3.3 V) may be used at a time Defaults to a static IP when directly connected to a computer DHCP is recommended when used with routers or LANs Programming MethodThis module does not include a USB interface. Programming requires an external USB-to-UART adapter (such as CP2102, CH340, or FTDI) and access to the ESP32 boot pins.Firmware configuration is typically performed using AT commands or ESP32-compatible development tools. �� Package Includes 1 × WT32-ETH01 ESP32 Ethernet Wi-Fi Bluetooth Gateway Module
