What Chip Shortage? How We Use Zephyr for Truly Modular Hardware
summary
Claim: Zephyr plus careful hardware choices let a single enclosure become a swappable system. Built an Aludel modular platform with click/Feather headers, faceplates, BME280 sensors and a W5500 Ethernet module, and it works — teams swap sensors, radios and MCUs (four different microcontroller boards supported in this project) by changing board overlays and comp files rather than main C. Uses device tree overlays and per-board comp files, CI builds multiple firmware images, and field tagging routes updates to the right hardware.
