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