## Description

## Overview

The LILYGO T-Camera S3 combines the Espressif ESP32-S3FN16R8 with an OV2640 2-megapixel camera sensor (UXGA 1622×1200) to create a compact WiFi camera development board. The ESP32-S3's dual-core Xtensa LX7 at 240MHz, combined with 8MB PSRAM for frame buffering and 16MB flash for firmware storage, handles JPEG streaming and real-time video processing without external hardware.

The onboard 0.96-inch SSD1306 OLED (128×64) provides status output such as IP addresses, stream stats, or sensor readings. WiFi 802.11 b/g/n enables live MJPEG streaming over a local network, and BLE 5.0 supports Bluetooth proximity and configuration applications.

The board uses native USB-C on the ESP32-S3 for programming and serial debug, eliminating the need for a separate USB-UART bridge. Compatible with the ESP-WHO computer vision framework, Arduino ESP32, and PlatformIO. Popular for doorbell cameras, baby monitors, time-lapse photography, and machine vision experimentation.
