Standard Expansion Shield for WRTnode OpenWRT Development Board

The Standard Expansion Shield for WRTnode is a dedicated add-on board designed to expand the peripheral interfaces of your WRTnode OpenWRT development board. It provides essential wired networking, USB host ports, and standard hardware bus breakouts for makers, students, and embedded developers.

Stackable board layout

This shield stacks directly onto compatible WRTnode OpenWRT development boards to expand functionality without cluttering your build.

Fast Ethernet connectivity

An onboard RJ45 port provides 100M Ethernet capability for reliable wired network access and embedded networking experiments.

Four USB host ports

The board incorporates four standard USB ports, allowing you to connect flash drives, input devices, or other USB peripherals to your system.

Sensor and bus interfaces

Pin breakouts offer direct access to UART, I2C, and SPI communication lines for interfacing with external microcontrollers and sensor modules.

GPIO and dual voltage rails

General-purpose input/output (GPIO) headers are exposed alongside integrated 5V and 3.3V power access lines to power auxiliary circuitry.
