It also has a connector for an external antenna, as well as an internal antenna that is etched onto the circuit board. The underside of the circuit board has the ESP32-S module. You’ll also note a square white LED on the top of the module, this can act as a “flash” for illuminating the subject you are trying to view with the camera. The “top” of the board has the connector for the camera module, as well as the microSD (sometimes called “TF”) card socket. One thing to note about this module is that it has components on both sides of the printed circuit board. Here is the pinout of the ESP32-CAM Module: This will be described further on in this article. In order to program this device you’ll need to make use of an FTDI adapter. Many of the GPIO pins are used internally for the camera and the microSD card port.Īnother thing missing from the ESP32-CAM module is a USB port. The ESP32-CAM module has fewer I/O pins than the previous ESP-32 module we looked at. Not bad for a board that costs about ten dollars, including the camera! Examining the ESP32-CAM After you get the hang of programming the device you’ll find that it is very easy to use. The sample software distributed by Espressif includes a sketch that allows you to build a web-based camera with a sophisticated control panel. It’s inexpensive and easy to use, and is perfect for IoT devices requiring a camera with advanced functions like image tracking and recognition. The ESP32-CAM is a full-featured microcontroller that also has an integrated video camera and microSD card socket. Read on and see how you can put it to use. This amazing little module packs a lot of power and features into a small package.
