Eport-E20 FreeRTOS Embedded TTL Serial to Ethernet TCP/IP Server Module 3.3V Support DHCP Telnet for MCU, 10PCS Pack

The Eport-E20 is a compact embedded serial-to-Ethernet network server module powered by mature FreeRTOS system, specially developed for MCU integration and secondary development. Adopting universal 3.3V TTL voltage level, it converts UART serial data into standard TCP/IP Ethernet signals to realize remote network data transmission for embedded devices.

This converter supports DHCP automatic IP acquisition and Telnet remote parameter debugging, equipped with TCP Server, TCP Client and UDP transparent transmission modes. Users can quickly set serial baud rate, network address and communication rules via AT commands or built-in web page, significantly cutting development time of IoT control equipment.

With small size, low power consumption and strong anti-interference capability, the module maintains steady long-term data communication. This 10-units bulk pack effectively reduces purchasing cost for system integrators and mass production. It fits widely in smart instruments, remote data collection, industrial embedded control and other miniature IoT networking devices, supporting continuous stable operation for long-term industrial use.
