Eport-E20 Embedded TTL Serial to Ethernet Module FreeRTOS TCP/IP Server with DHCP Telnet, 5PCS Pack

The Eport-E20 is a miniature embedded TTL serial to Ethernet network server module running on mature FreeRTOS operating system, designed for seamless integration with MCU control boards. It adopts 3.3V TTL voltage level to match most mainstream microcontrollers, converting serial UART data into standard TCP/IP Ethernet signals for remote data transmission.

This embedded module supports DHCP automatic IP assignment and Telnet remote debugging, alongside multiple working modes including TCP Server, TCP Client and UDP transparent transmission. Developers can quickly configure communication parameters via serial AT commands or webpage, greatly shortening secondary development cycles.

With tiny embedded size and low power consumption, the Eport-E20 delivers reliable long-distance data communication. This 5-unit pack lowers procurement costs for engineering development and mass production. It is widely utilized in smart equipment, remote data acquisition, industrial control embedded systems and various small IoT networking devices, supporting stable long-term continuous operation.
