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

Eport-E20 is a miniature embedded serial network server module based on FreeRTOS real-time operating system, designed for secondary development with microcontrollers. It converts 3.3V TTL UART serial data into standard TCP/IP Ethernet data to realize remote data transmission for embedded hardware.

The module supports DHCP automatic IP address acquisition to skip manual static IP setup, and Telnet remote access for convenient parameter modification. It provides multiple transmission modes to meet diverse data upload and control demands. All serial and network parameters can be configured via AT commands or built-in web page, greatly shortening development cycles for engineers.

Compact size and low power design make it easy to integrate into smart sensors, industrial controllers and small IoT devices. This 10-units bulk pack lowers procurement expenses for engineering teams and mass production. It works reliably for long-term continuous data transmission in data acquisition, intelligent equipment control and embedded networking scenarios.
