Raspberry Pi Pico Ethernet to UART HAT expansion board (20410)

Raspberry Pi Pico Ethernet to UART HAT (20410 ) is an Ethernet (10/100 Mbps) to UART converter for Raspberry Pi Pico. Supports 2-channel transparent data transfer from Ethernet to UART

The location of the connector pins on the back of the board allows you to connect Raspberry Pi Pico expansion boards with the appropriate connector at the same time.

Note: The Raspberry Pi Pico and Pico-LCD-1.14 are for demonstration purposes only and are not included in the package.

Application scenario: Four modes of operation: TCP CLIENT, TCP SERVER, UDP CLIENT, UDP SERVER.

Main features:

• Standard Raspberry Pi Pico connector, supports Raspberry Pi Pico series
• Built-in transparent Ethernet-UART transceiver, 2-channel UART, standalone transparent transmission for each channel
• Built-in jumpers for pin configurations
• Integrated Ethernet MAC and PHY layers
• Bidirectional transparent data transfer between UART and Ethernet
• 10/100M, full-duplex/half-duplex Ethernet interface with auto-negotiation, 802.3 compliant
• Auto-MDI/MDIX, automatic cable type detection and switching
• Supports DHCP automatically acquired IP and DNS domain access
• Configuration of network parameters, such as chip mode, port, IP address, through host computer software or UART command
• Four modes: TCP CLIENT, TCP SERVER, UDP CLIENT, UDP SERVER.
• Full-duplex or half-duplex UART communication, supports automatic RS485 RX/TX switching (external RS485 controller required)
• Supports virtual serial port software (included)
• Supports KEEPALIVE mechanism
• Comes with development resources and manual (examples for Pico/Raspberry Pi/Arduino/STM32)
