E1M-AEN is the Alif Ensemble SoM family on the 35×35 mm E1M form factor.

Reading order

  1. One-pager — docs/soms/aen.md — what’s on the SoM, what the carrier sees, what’s optional.
  2. Bring-up — docs/getting-started.md §4..5 — Zephyr toolchain, first flash, sanity blink.
  3. Reference examples — examples/gpio-button-led/, examples/i2c-scanner/, examples/rtc-clock/ — same code runs across every SoM family.
  4. Alif HAL upstream — sdk-alif is now a first-class consumer in west.yml; the SDK’s hal_alif is promoted to first-class upstream (see CHANGELOG §C.41/§C.42).
