Overview
The ESP32-CAM is a small-form-factor camera module that can operate independently as a least-cost system. It features the powerful ESP32 dual-core processor, a 2-Megapixel OV2640 camera, and an onboard MicroSD card slot for local image storage. It also includes a high-brightness Flash LED, making it capable of capturing photos and video even in low-light conditions. It is fully compatible with the Arduino IDE and ESP-IDF, making it a favorite for “Smart Home” developers across Pakistan.
