Ethernet To UART Converter For Raspberry Pi Pico, 10/100M Ethernet, Enabling Network Communication Through UART

Features:

  • Standard Raspberry Pi Pico header, supports Raspberry Pi Pico series
  • Onboard Ethernet to UART transparent transceiver, 2-CH UART, standalone transparent transmission for each channel
  • Onboard jumpers for pin configurations
  • 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
  • Full-duplex or half-duplex UART communication, supports RS485 RX/TX auto switch (external RS485 controller required)
  • Supports virtual serial port software (provided)
