The ESP32-Stick-PoE-A-Cam(N16R8) is an open-source ESP32-S3 development board with Ethernet, camera, and active PoE support designed for machine learning applications. Compared to similar boards like M5Stack M5PoECAM-W V1.1 and the Waveshare ESP32-S3-ETH, this board features 17 usable GPIO, active PoE (IEEE 802.3af) with 700mA power delivered, built-in USB-UART, and pin-to-pin compatibility across Stick-Cam boards.
Built around the ESP32-S3 SoC, this module supports OV2640 and OV5640 cameras and integrates the W5500 Ethernet controller and Si3404-A PoE chip for power and connectivity. The board has a total of 36 GPIOs, of which 17 are free when using Ethernet and a camera. Applications include remote surveillance, smart home automation, edge AI processing, and other IoT applications.

As the board uses an ESP32, it can be programmed with Arduino IDE, PlatformIO, or ESP-IDF. Prokyber also includes a basic camera+ethernet PlatformIO example, along with Machine Learning tutorials available on GitHub.
Prokyber mentions that the board is pin-to-pin compatible with other ESP32-Stick-Cam boards, but it’s not clear which ones, so it’s safe to assume they are talking about boards designed by them in the same series, not those from other manufacturers. As a side note, it has features and a form factor similar to the AI-On-The-Edge-Cam board we’ve just covered, and that is specifically designed for reading meters with RGB LEDs acting as a flash.
The ESP32-Stick-PoE-A-Cam(N16R8) board is available on Tindie for $27.00. The schematic for this board is also available on the same page, but I don’t know why it’s called a “datasheet”.
