CH9121 2-CH UART To Ethernet Converter

CH9121 Serial to Ethernet module. Tích hợp bên trong giao thức TCP/IP, cho phép truyền dữ liệu trong suốt hai chiều giữa UART TTL và RJ45 Ethernet, có 4 chế độ làm việc TCP CLIENT, TCP SERVER, UDP CLIENT, UDP SERVER, tốc độ truyền nhận dữ liệu nhanh, tiêu thụ điện năng thấp, ổn định, dễ dàng cấu hình bằng phần mềm.

Giải pháp cho nhiều ứng dụng trong lĩnh vực kết nối với các thiết bị từ xa, thu thập dữ liệu, tự động hóa, IoT...  kết nối các thiết bị nhúng vào mạng mà không cần giao tiếp trực tiếp Ethernet.

Function
  • 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/PIC/AVR...)
  • Voltage supply: 3.3V/5V
  • Operating current: 140ma
  • Uart baudrate: 300bps ~ 921.6kbps
  • Storage temperature: -55℃ ~ 125℃
  • Operating temperature: -40℃ ~ 85℃
  • Dimensions: 53.00 × 22.00mm
