Ethernet to UART Converter for Raspberry Pi Pico

The Waveshare Ethernet to UART Converter for Raspberry Pi Pico is a compact Ethernet-to-UART converter module designed for seamless integration with the Raspberry Pi Pico. It enables network communication via UART, supporting 10/100M Ethernet connections. The module features two independent UART channels, allowing for transparent data transmission. It supports four operating modes: TCP Client, TCP Server, UDP Client, and UDP Server.

Key Features

• Compatibility: Designed for Raspberry Pi Pico series with a standard header for direct attachment.
• Ethernet Interface: 10/100M Ethernet with full-duplex/half-duplex auto-negotiation, compliant with IEEE 802.3 standards.
• Dual UART Channels: Two independent UART channels for transparent data transmission.
• Operating Modes: Supports TCP Client, TCP Server, UDP Client, and UDP Server modes.
• Configuration: Network parameters configurable via host software or UART commands.
• Auto-MDI/MDIX: Automatically detects and switches cable types.
• DHCP and DNS Support: Automatically obtains IP addresses and supports domain name access.
• RS485 Support: Full-duplex or half-duplex UART communication with RS485 RX/TX auto switch (external RS485 controller required).
• Indicators: Onboard LEDs for power, UART connection status, and CH9121 running status.
• Power Supply: Compatible with 3.3V and 5V systems.
