ESP32-STICK-CAM

Description

ESP32-Stick-Cam – development board with camera, Ethernet and PoE support

ESP32-Stick-Cam is a powerful development board based on the ESP32-S3 chip. It supports Ov2640 and Ov5640 cameras, Ethernet via W5500 chip, and optionally PoE (active or passive). The board is fully programmable using Arduino IDE and supported in the ESPHome environment. All variants share the same dimensions and pinout, ensuring firmware and hardware compatibility.

Main Features

• ESP32-S3-WROOM-1 (N16R8) with 16MB Flash and 8MB RAM
• Supports Ov2640 and Ov5640 cameras
• 36 GPIOs (17 are free from Ethernet and camera usage)
• W5500 Ethernet chip
• USB-C connector for power, programming, and communication (USB2)
• Integrated CH340G USB-UART converter – no external adapter needed
• AI, machine learning, and neural network ready
• USER LED (GPIO2), Reset button and User button (GPIO0)
• 5V output for powering peripherals
• Plug-and-play programming with no additional components

Power Options

• USB-C (5V)
• External 3.3V or 5V input via pins
• Passive PoE (LM2576HVS, 3.3–57V) – PoE-P version
• Active PoE (Si3404-A, 5V) – PoE-A version
• 3.3V rail (AMS1117): 700 mA
• 5V rail (LM2576HVS or Si3404-A): 700 mA

Variants

• Esp32-Stick-Eth-Cam – no PoE, powered via USB or external pins, no headers soldered
• Esp32-Stick-PoE-P-Cam – passive PoE (LM2576HVS), no headers soldered
• Esp32-Stick-PoE-A-Cam – active PoE (Si3404-A), headers soldered

Compatibility

All variants share the same size, pinout, and chip, making them interchangeable. Firmware developed for one board is fully compatible with all others.
