How to Build a Thread Border Router with a W5500 Wired Backbone Using Espressif's esp-thread-br SDK Overview Thread is a low-power wireless mesh network (802.15.4) for IoT devices, and the device that links this mesh to a home or building's regular IP network (Wi-Fi/Ethernet) is a Thread Border Router (BR). This project is Espressif's open-source Thread Border Router SDK, implementing a BR by layering the OpenThread stack on an ESP32-S3 (main SoC) + ESP32-H2 (802.15.4 RCP) structure. A BR's performance hinges on the stability of its backbone (upstream network) connection. This SDK supports…
