ESP32 Comparison Chart
The ESP32 family has expanded into several processor families, each designed for different applications. While they share many similarities, they differ significantly in processor architecture, wireless capability, performance, GPIO availability, and intended use.
This page provides a high-level comparison of the major ESP32 processor families commonly encountered in DIY holiday lighting projects.
