2-канальный преобразователь UART Ethernet

2-CH UART TO Ethernet Converter

The 2-CH UART TO ETH provides an easy way to communicate between UART TTL and RJ45 Ethernet, allowing bi-directional transparent data transmission. It is easy to use, along with features like fast data rate, low power consumption, high stability, suits applications such as safety & security, IoT, and so on.

• Embedded Ethernet MAC and PHY layers
• Bi-direction transparent data transmission between UART and Ethernet
• 10/100M, full-duplex/half-duplex auto-negotiation Ethernet interface, 802.3-compliant
• Auto-MDI/MDIX, detect and switch cable type automatically
• Supports DHCP auto-obtained IP and DNS domain access
• Network parameter configuration like chip operating mode, port, IP, via host computer software or UART command
• Four operating modes: TCP CLIENT, TCP SERVER, UDP CLIENT, UDP SERVER
• 2-CH UART concurrent operation, standalone transparent transmission for each channel
• Full-duplex or half-duplex UART communication, supports RS485 RX/TX auto switch
• Supports virtual serial port software (provided)
• KEEPALIVE mechanism support
• Comes with development resources and manual (examples for Pico/Raspberry Pi/Arduino/STM32)

Control Interface

Supports Host Boards Including Raspberry Pi/Arduino/STM32...

• 5V / 3V3: power positive, use any pin of 5V/3.3V pins for power supply
• GND: ground
• RST1: external reset input, low active
• RESET: restore to factory setting, detected when chip poweron, low active
• TXD1: asynchronous UART 1 data output (enabled by default)
• TXD2: asynchronous UART 2 data output (disabled by default)
• RXD1: asynchronous UART 1 data input (enabled by default)
• RXD2: asynchronous UART 2 data input (disabled by default)
• CFG0: UART config mode, low level to enter configuration, high level to exit configuration
• RUN: Operating status indicating pin
• DIR1: UART 1 RS485 RX/TX switch (connects to external RS485 controller)
• DIR2: UART 2 RS485 RX/TX switch (connects to external RS485 controller)
