Overview

PP-Ethernet-UART-HAT is a compact yet powerful Ethernet-to-UART converter. It is equipped with WIZnet's powerful Ethernet conversion chip, the W55RP20.

This module functions as a protocol converter, transforming data transmitted from serial devices into TCP/IP data for network transmission and converting TCP/IP data received over the network back into serial data for the serial devices. Additionally, it allows for easy module control with simple pin settings. Since it comes preloaded with powerful firmware, everything is ready to go upon installation. You only need to configure the IP using a tool, and it's ready for immediate use.

Interface

• 3.3V : Main power 3.3V input
• GND : Ground
• UART : Tx, Rx, RTS, CTS
• RP_BOOT (SW) : Switch for MCU boot mode when uploading firmware via USB
• nRST : MCU reset pin
• FACT RST : Pin for resetting all IP settings to factory defaults
• AT Mode : Pin for entering AT mode for IP configuration via UART
