ماژول وایفای و بلوتوث ESP32-CAM همراه با دوربین با ابعاد کم و مصرف توان پایین با پروتکل های ارتباطی رایج مثل وای فای بهترین گزینه برای استفاده در پروژه های اینترنت اشیا می باشد.

در پروژه هایی که نیاز به استفاده از یک دوربین کم حجم با توان مصرفی پایین باشد این ماژول به عنوان اولین گزینه می باشد. تأمین و واردات قطعات هایتک را به ما بسپارید.

چیپ وای فای موجود بر روی ماژول از یک میکروکنترلر دو هسته با حداکثر کلاک 240MHz با توان پایین بهره می برد. پشتیبانی از کارت TF، پشتیبانی از چندین حالت Sleep و استفاده از تکنولوژی smart config از جمله ویژگی های این ماژول می باشد.

Introduction

The ESP32-CAM is a very small camera module with the ESP32-S chip that costs low. Besides the OV2640 camera and several GPIOs to connect peripherals

it also features a microSD card slot that can be useful to store images taken with the camera or to store files to serve to clients. This development board is an ESP32 based board with WiFi and Bluetooth and has a built-in camera.

In addition, the board also has a micro SD card connection. Please ensure that the module input power is at least 5V 2A, otherwise, the image will unstable.
ESP32 GPIO32 pin controls camera power. When the camera is working, please pull GPIO32 low.
Since IO0 is connected to the camera XCLK, please leave IO0 floating when using it. Do not connect high and low levels.
The factory has the default firmware, no additional download is available. Please handle it carefully if you need to re-burn other firmware.
