## Description

This is an embedded serial-to-Ethernet module based on the ESP32 series, also can be called a gateway. The module integrates an optimized TCP/IP protocol stack, which is convenient for users to easily complete the networking functions of embedded devices while reducing development time costs. The ESP32 series of ICs are SOCs 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 has diverse and powerful functions. It supports four working modes: TCP Server, TCP Client, UDP Server, and UDP Client; supports serial port, WiFi, Ethernet, and Bluetooth four data ports for pairwise combination, and 6 data transparent transmission modes; supports WiFi to connect to the Internet or local area network through a router, establish a TCP/UDP connection, and access the user's designated server.; support user's secondary development based on ESP32.The module can be used in agriculture, industry, medical equipment, and other fields. It is an excellent choice for data transmission in IoT scenarios, such as smart agricultural sensor data monitoring. The module can collect and transmit data from sensors such as air temperature and humidity, soil temperature and humidity, soil PH value, and carbon dioxide concentration to the server. The module has abundant IO ports, which can realize the functions of temperature acquisition and mutual control of ventilation and heating equipment. Note: The applicable temperature of the product is -20°C~+70°C Features Supports complete TCP/IP protocol stackAbundant wireless communication interfaceMultiple working modes are available Applications IoT scenariosSmart agricultural sensor data monitoring Specification Wi-Fi RF certification: FCC/CE/RoHSProtocol: 802.11 b/g/n/e/i(802.11n, up to 150Mbps) A-MPDU and A-MSDU aggregation, 0.4 second guard interval supportFrequency Range: 2.4~2.5GHzBluetoothProtocols: Compliant with Bluetooth V4.2 BR/EDR and BLE standardsRadio frequency: NZIF receiver with -97dBm sensitivityHardwareNetwork port specifications: RJ45, 10/100Mbps, cross-direct connection adaptiveSerial baud rate: 80~5000000On-board Flash: 32MbitOperating Voltage: 5V or 3.3V power supply (optional)Working current: Average 80mASupply current: Minimum 500mAWorking temperature range: -40°c ~ +85°cAmbient temperature range: Normal temperaturePackaging: Half pad/ through-hole connector (optional)SoftwareWi-Fi mode: Station/ SoftAP/ SoftAP+station/ P2PWi-Fi security mechanism: WPA/ WPA2/ WPA2-Enterprise/ WPSEncryption type: AES/ RSA/ ECC/ SHAFirmware upgrade: Remote OTA upgrade via networkSoftware development: SDK used for further developmentNetwork protocol: IPv4, TCP/ UDPIP access methods: Static IP, DHCP (default)Simple transmission mode: TCP Server/ TCP Client/UDP Server/ UDP ClientUser configurations: AT+ commands set Documents AT Command Examples of WT32-ETH01 Wired Module_v1.1.pdfAT Commands of WT32-ETH01 Wired Module_v1.1.pdfWT32-ETH01_datasheet_V1.1.pdf Shipping List Embedded Serial to Ethernet Module x1
