Dual-RJ45 Networked I/O Controller
ESP32-based controller with dual RJ45 ports for daisy-chained wired networking and a 12V power input, built as a networked I/O node for distributed building or industrial automation systems.
Project overview
ESP32-based controller with dual RJ45 ports for daisy-chained wired networking and a 12V power input, built as a networked I/O node for distributed building or industrial automation systems.
Engineering approach
Connected products live or die on power efficiency and radio performance, so RF-aware layout and antenna matching are treated as first-class design constraints. On this board, that translates into a component set built around ESP32, 2x RJ45 and 12V Input, with layout and stack-up decisions driven by radio layout, antenna placement, power budget, and reliable wireless connectivity in real-world conditions.
