1. Hardware Platforms

The Espressif Thread Border Router supports both Wi-Fi and Ethernet interfaces as backbone link.

1.1. Wi-Fi based Thread Border Router

The Wi-Fi based ESP Thread Border Router consists of two SoCs:

The host Wi-Fi SoC, which can be ESP32, ESP32-S and ESP32-C series SoC.

The radio co-processor (RCP), which is an ESP32-H series SoC. The RCP enables the Border Router to access the 802.15.4 physical and MAC layer.

Espressif provides a Border Router board which integrates the host SoC and the RCP into one module.

1.2. Ethernet based Thread Border Router

Similar to the previous Wi-Fi based Thread Border Route setup, but a device with Ethernet interface is required.

Espressif provides a Sub-Ethernet daughter board, which works with the ESP Thread Border Router board to extend Ethernet interface.
