ESP32-CAM WiFi Bluetooth Development Board with OV2640 Camera

This board puts an ESP32's dual-core processor, WiFi and Bluetooth radios, and a 2MP camera on one small module, which is the combination that made ESP32-CAM the default choice for DIY camera projects - a single board handles capturing an image, processing it, and sending it over WiFi without a separate camera interface board. The 4MB external PSRAM alongside 520KB internal SRAM gives enough headroom for JPEG capture and buffering that a bare ESP32 without PSRAM would struggle with.

A microSD slot (up to 4GB) lets a project store captured images locally rather than needing constant network connectivity, useful for a security camera that logs even during a WiFi dropout. The full ESP32 peripheral set - UART, SPI, I2C, PWM, ADC, DAC - remains available alongside the camera function, so it is not a camera-only board but a general ESP32 dev board that happens to have a lens attached.

Common builds are WiFi security cameras, IoT image-capture projects, and any build needing both general ESP32 compute and a camera in one compact module.
