ESP32-P4 vs ESP32-S3: Choosing for Displays, Cameras, and Wireless Products
Use display and camera interfaces, RAW/ISP or H.264 needs, wireless architecture, and matched-workload tests to decide which ESP32 platform to prototype first.

What Edge AI Models Can ESP32-P4 Run? From ESP-DL Support to Real-Time Vision Validation
An ESP-DL model listing may say “ESP32-P4 supported,” but that does not answer the question a camera product has to answer.

ESP32-P4 LVGL HMI: Budget Frame Buffers Before Tuning Refresh and Tearing
An 800 × 480 panel in RGB565 needs 768,000 bytes for one uncompressed frame. Two panel frames alone consume about 1.46 MiB, before LVGL draw buffers, fonts.

Offline RAG for Equipment Manuals: Versioned Evidence Before Answers
A technician asks how to reset an E42 alarm. A local model produces a convincing procedure, but cannot identify the machine variant, manual edition, or page it used.
