The Embedded Serial to Ethernet Module is a versatile gateway based on the powerful ESP32 series that simplifies connecting your serial devices to networks.
This module comes with an optimized TCP/IP protocol stack that makes it easy to add networking capabilities to your embedded projects while saving development time and costs.
The heart of this module is the ESP32 system-on-chip that combines 2.4GHz WiFi and Bluetooth dual-mode connectivity with exceptional performance, stability, and remarkably low power consumption.
Whether you're a student working on an IoT project or a shop owner looking to offer smart connectivity solutions, this module provides an accessible way to bridge traditional serial devices with modern networking.
This IoT communication module offers impressive versatility with four working modes (TCP Server, TCP Client, UDP Server, and UDP Client) and supports six different data transparent transmission modes.
It allows you to create powerful connections between serial ports, WiFi, Ethernet, and Bluetooth interfaces in various combinations. The module excels in practical applications like smart agriculture, where it can collect and transmit data from sensors measuring air temperature, humidity, soil conditions, pH values, and carbon dioxide levels directly to a server.
With its abundant IO ports, the module can also control ventilation and heating equipment based on temperature readings.
This makes it an ideal solution for anyone looking to implement ESP32 gateway functionality in IoT scenarios without dealing with complex networking protocols.
Note: The applicable temperature of the product is -20°C~+70°C
