Description:
This product is a serial to Ethernet module that can achieve bidirectional transparent data transmission between TTL serial port and RJ45 network port.

Simple operation, fast speed, low power consumption, high stability, and can be used in fields such as security and IoT

Features:
Equipped with Ethernet Media Transport Layer (MAC) and Physical Layer (PHY)
Implement bidirectional transparent transmission of serial port data and network data
Supports 10/100M, full duplex/half duplex adaptive Ethernet interface, compatible with 802.3 protocol
Supports automatic conversion of MDI/MDIX lines
Supports DHCP to automatically obtain IP addresses and DNS domain name access
Network parameters such as chip working mode, port, IP, etc. can be set through upper computer software and serial port commands
The working mode supports four modes: TCP CLIENT, TCP SERVER, and UDP CLIENT, UDP SERVER
Supports simultaneous operation of two serial ports and independent transparent transmission
The serial port supports full duplex and half duplex serial communication, and supports automatic switching of RS485 transceiver
Support and provide virtual serial port software
Support for KEEPALIVE mechanism
Provide comprehensive supporting documentation manuals (Pico/Raspberry/Adjuino/STM32 sample programs and user manuals, etc.)
