MINI Border Router

MINI Border Router
Project Overview:
This project involves creating a MINI border router solution based on Espressif's ESP32-S3 and ESP32-H2 (Wi-Fi and 802.15.4), utilizing services such as LCSC PCB, 3D printing, and the LCSC online store.
The bilibili video link
project features compatibility
with ESP Thread Border Router,

bidirectional IPv6 connection
service discovery,
multicast forwarding,
NAT64
RCP update,
RF coexistence,
and a web-based graphical user interface.

Software description: Espressif ESP Thread Border Router SDK, Visual Studio Code + ESP IDF development environment. Physical demonstration . Notes : Difficulty of replication: ⭐⭐⭐ This project has many 0402 components, and the density is average. Please evaluate carefully before replication. The RJ45 network port has a corner that interferes with the bevel of the shell, requiring manual cutting of the network port plastic. Cost reference: Standard version, Simplified version, PCB'A ￥93 ￥55 (no PoE module) , Antenna ￥1.36 ￥1.36 , Heatsink ￥1.3 ￥1.3, Shell ￥28.7 ￥8.7 (unpainted) , Feet ￥0.11, None. Total ￥124.47 ￥66.36
