Build Connected Camera and IoT Projects The OpenELAB ESP-CAM development board uses the ESP32-S3-N16R8 platform with 16MB flash and 8MB PSRAM. It combines programmable wireless connectivity with a camera ribbon connector, making it a starting point for image capture, local-network camera experiments, connected sensors and embedded vision learning. Choose the correct package: the mainboard-only option does not include a camera. Select the OV5640 or OV3660 bundle when you need the corresponding image sensor. This is a development board requiring firmware and setup, not a ready-to-use security camera. Variants and Package Contents Option Included core hardware SKU CAM Mainboard + OV5640 1 mainboard and 1 OV5640 camera; sensor resolution up to 2592 x 1944 (5MP class). TB-ESP32S3-OV5640 ESP32-S3-N16R8 CAM Mainboard 1 mainboard only; camera not included. TB-ESP32S3-N16R8-MB CAM Mainboard + OV3660 1 mainboard and 1 OV3660 camera; sensor resolution up to 2048 x 1536 (3MP class). TB-ESP32S3-OV3660 Sensor resolution is not a promise of full-resolution video streaming performance. Actual image size and frame rate depend on firmware, format, memory settings and network conditions. The supplier photograph shows loose header strips; confirm header inclusion and soldering status if these matter to your assembly. USB cables, power adapters, storage cards and enclosures are not listed as included. Key Features 16MB flash: space for application firmware and project data, subject to your partition configuration. 8MB PSRAM: additional working memory for camera frame buffers and larger embedded workloads; enable it in your development configuration. 2.4GHz Wi-Fi and Bluetooth LE: build networked projects and BLE control interfaces without adding a separate radio module. Dual-core ESP32-S3 processor: supports embedded control and signal-processing development. Vision or voice applications still require suitable software and any additional hardware. Onboard PCB antenna, two USB-C connectors and BOOT/reset controls: accessible hardware for programming and experimentation. Check the board's port labels and revision-specific documentation before connecting.

Do not use this as a confirmed overall enclosure dimension; measure the complete supplied board and connected camera before mechanical integration. Development and Wiring Notes ESP-IDF and Arduino-ESP32 provide development routes for the ESP32-S3. Select the correct processor, flash size and PSRAM configuration, and use a camera pin map for this exact PCB revision. An example for a different ESP-CAM board is not automatically pin-compatible. Start with JPEG capture at a modest resolution before increasing image size or streaming load. Espressif's camera driver supports OV5640 and OV3660; driver support alone does not establish electrical compatibility with every camera module sold under those sensor names. Camera signals, USB and memory can occupy pins that appear on the headers. Treat the board schematic as the reference rather than assuming every labeled pin is free. Use a stable supply and a data-capable USB cable; disconnect power before inserting or removing a camera ribbon. Use level shifting for peripherals with incompatible logic levels.

Frequently Asked Questions Does every option include a 5MP camera? No. Only the OV5640 bundle includes the 5MP-class sensor. The OV3660 bundle includes a 3MP-class sensor, and the mainboard-only option has no camera. OV2640 is mentioned in the supplier's wider documentation but is not a selectable bundle here. What does N16R8 mean for this board? This configuration has 16MB flash and 8MB PSRAM. Flash stores firmware and data, while PSRAM provides additional working memory. The two are not interchangeable. Can it connect to a Bluetooth speaker or a 5GHz router? It does not support Bluetooth Classic audio profiles or 5GHz Wi-Fi. Use a compatible Bluetooth LE application or a 2.4GHz Wi-Fi network. Is autofocus or 1080p at 30fps guaranteed? No. Autofocus depends on the supplied lens assembly and driver support. Video performance depends on the complete implementation, not just the sensor's standalone capabilities. Does it include face recognition, voice control or cloud recording? No preconfigured service is promised. These are software-development possibilities, not included turnkey features. Voice projects need suitable audio hardware, and cloud services may require separate accounts or subscriptions.
