5 Pack Eport-E20 TTL Serial to Ethernet Embedded Module, FreeRTOS TCP/IP Network Server Converter, 3.3V MCU Serial Module Supports DHCP & Telnet for Embedded IoT Projects

Eport-E20 is a mini embedded serial-to-Ethernet conversion module built with mature FreeRTOS TCP/IP protocol stack, specially designed for connecting MCU TTL serial ports to Ethernet networks to realize transparent data transmission. Working under 3.3V low voltage power supply, it matches the voltage level of most mainstream microcontrollers without extra level conversion circuits.

This embedded network module supports multiple mainstream communication modes including TCP Server, TCP Client, UDP and Telnet, and carries DHCP function to automatically obtain IP addresses, reducing complex static IP configuration work during batch equipment deployment. It realizes two-way transparent transmission between serial port and Ethernet, enabling remote data collection, equipment control and signal uploading for intelligent devices.

With ultra-small PCB size, it is easy to integrate into custom circuit boards of smart sensors, industrial controllers, IoT terminals and embedded development equipment. The 5-piece bulk pack provides sufficient modules for mass production testing, prototype development and small-batch intelligent hardware manufacturing. No complicated peripheral circuits are required, greatly shortening the development cycle of network-connected MCU products.
