Advantech has unveiled the AFE‑E420, a compact and highly integrated single‑board computer tailored for electric vehicle (EV) charging stations and energy storage systems. Based on the NXP i.MX 93 SoC, it combines an Arm® Cortex®‑A55 core for high performance with a Cortex‑M33 co‑processor for real‑time control tasks, and introduces on‑chip Arm Ethos‑U65 microNPU for efficient edge‑level machine learning while maintaining low power consumption and heat generation. Security is enhanced through EdgeLock® secure enclave integration, ensuring robust protection in field deployments.
