₹350–₹700
Camera + Wi-Fi SoC for vision IoT (stream, QR, crude detect).
Interface: Wi-Fi, UART program, GPIO
ESP32 can run similar Wi-Fi lab patterns; pin numbers differ from NodeMCU silk.

Concept
ESP32 plus OV2640 camera, programmed over UART with a USB-MB dongle.
A little theory
JPEG from camera over SPI-like DVP. GPIO 0 must be held LOW to flash. In the classroom, treat ESP32-CAM (OV2640) + MB programmer as a advanced part using Wi-Fi, UART program, GPIO. Typical India street price is about ₹350–₹700. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
How it works in a project
Use ESP32-CAM-MB, example “CameraWebServer”, join Wi-Fi, open the stream URL.
