Why TinyML on ESP32-S3 Bottlenecks on Memory, Quantization, and Real-Time Inference

ESP32-S3 can run TinyML, but production success depends less on AI instructions alone and more on SRAM, tensor arena sizing, INT8 quantization, operator support, PSRAM latency, sensor pipelines, and real-time inference budgets. This article explains the practical bottlenecks and boundaries.

High-Density LED Control with ESP32 RMT and WLED

Driving large WS2812 or SK6812 installations with ESP32 and WLED is not just an MCU performance problem. The real constraints are LEDs per output, RMT interrupt or DMA behavior, 800 kHz serial timing, power injection, Wi-Fi load, and multi-controller sync. This article gives a practical architecture guide.
