Ethernet To UART Converter For Raspberry Pi Pico
Enabling network communication through UART
- UART Baudrate: 300-921kbps
- Operating Current (A): 140mA
- Operating Temperature Range (C): -40 to 85
- Operating Voltage(V): 3.3 to 5
Features:
- Standard Raspberry Pi Pico header
- Onboard Ethernet to UART transparent transceiver
- Supports DHCP auto-obtained IP and DNS domain access
- Four operating modes: TCP CLIENT, TCP SERVER, UDP CLIENT, UDP SERVER
The CH9121 is a transparent network serial port chip that supports bidirectional and transparent transmission of serial port data and network data. It supports four working modes: TCP CLIENT/SERVER and UDP CLIENT/SERVER. The serial port baud rate ranges from 300bps to 921600bps. Before using, you should set network and serial port parameters for the chip by the NetModuleConfig.exe software or serial commands. After the configuration is complete, the CH9121 saves the configuration parameters to the internal storage space. After the chip is reset, the CH9121 could work based on the saved configuration values.
Supports virtual serial port software (provided) and KEEPALIVE mechanism support. Full-duplex or half-duplex UART communication supports RS485 RX/TX auto switch (external RS485 controller required).
