Sensors
OV2640 camera

Turn a Seeed XIAO ESP32-S3 Sense into a working network camera in 20 minutes. The config sets up the OV2640 camera, a snapshot web server on port 8080, WiFi with a captive-portal fallback, and sane frame rates. It is the fastest way to see an ESP32 do something real — and every later solution builds on the same flash-and-configure workflow you learn here.

Maintained and field-tested by the Latent team.
