One Code Base, Multiple Targets
summary
Same code compiles and runs on three boards (Particle Xenon/nRF52840, nRF9160 Feather, Seeed LoRa E5) and across two Zephyr manifests by swapping a west manifest and running pristine builds. The demo wires an Air Quality Wing to measure PM2.5, temperature, humidity and VOC, uses the async UART API, and exposes platform-specific work: STM32 needs DMA slots/channels (rx/tx 21/22), nRF auto-merges MCUboot, and bootloader flashing paths differ.
