PP-Ethernet-UART-HAT – A Compact Yet Powerful Serial to Ethernet Converter
Looking to add Ethernet connectivity to your serial devices quickly and easily?
The PP-Ethernet-UART-HAT is a compact yet high-performance UART to Ethernet module designed to seamlessly integrate serial communication into modern network systems. Whether you’re working on industrial automation, IoT development, or legacy device upgrades, this module is a perfect fit.
Overview
The PP-Ethernet-UART-HAT is equipped with WIZnet’s cutting-edge Ethernet chip, the W55RP20, delivering reliable and efficient Ethernet-to-UART conversion.
It acts as a protocol converter, transforming data from serial interfaces into TCP/IP packets for network communication and vice versa. With preloaded firmware, there’s no need for complicated setup – simply configure the IP address using a tool, and you’re ready to go.
Key Features
- Bidirectional UART to Ethernet conversion
- Supports Modbus TCP and Modbus RTU/ASCII protocols
- Easily adds Ethernet functionality to existing serial devices
- 10/100Mbps Ethernet support with serial speeds up to 921kbps
- Secure device search with password protection
- AT command support over UART
- Configuration via PC tool or web interface
- Wide input voltage range: 5V to 50V
- Industrial operating temperature: -40 to 85°C
- Built-in ESD protection for enhanced durability
- Pre-assigned unique MAC address
Interface Overview
- 3.3V / GND: Power input
- UART (Tx, Rx, RTS, CTS): Serial communication
- RP_BOOT / nRST / FACT RST: Boot mode, reset, and factory reset pins
- AT Mode: Enables AT command configuration via UART
- SWD / USB: For firmware upload and debugging
Easy Control & Configuration
No additional software installation is needed to start using the module.
You can configure and control it in multiple ways:
- Via Ethernet using the Configuration Tool (TCP-based)
- Using AT Commands through the UART interface
- Through a Web-based Configuration Interface
This flexibility makes it ideal for both development and deployment scenarios.
Ideal Applications
- Adding Ethernet to industrial RS-232/RS-485 devices
- IoT gateways and sensor hubs
- Remote control and monitoring systems
- Serial device networking over TCP/IP
Conclusion
The PP-Ethernet-UART-HAT is a feature-rich, plug-and-play solution for anyone seeking to bridge the gap between serial communication and Ethernet networks. Its small form factor, powerful firmware, and flexible configuration options make it a go-to choice for engineers, developers, and system integrators.
