It aims to build a small-footprint security controller on an Arduino Uno (ATmega328P) using Rust in a no_std environment, and then extend it with wired Ethernet via a WIZnet W5500 module (SPI) so the device can publish events and accept commands over MQTT. It’s not presented as a finished “product”—it reads more like a…
