This Development Board Is An Upgraded Version Of The Esp32-Cam Development Board, Which Adds Psram. The Module Adopts Esp32 Low-Power Solution, Integrates Wifi And Bluetooth, And Can Operate Independently As The Smallest System.The Module Is Equipped With A Default 0V5640 Camera, Which, Combined With The Powerful Performance Of Esp32, Can Reach Up To 30 Fps In Vga Format. The Most Significant Feature Of This Upgrade Is The Addition Of 8Mb (Bytes) Of External Ram And Upgraded Tf Card Slot, Which Supports Users To Use Up To 32Gb Of Storage Cards And Can Capture Higher Pixels And Store More Images, Meeting Secondary Development Needs Of Users. And After Joining Psram, It Can Also Support The Recognition Framework Esp-Who, Which Is Suitable For Use In Iot And Smart Device Scenarios, Such As The Development Of Recognition Projects For Supermarket Lockers. MCU: ESP32-D0WDQ6: Frequency adjustable between 80-240MHz, integrated 2.4GHz Wi Fi and Bluetooth dual-mode, 40nm process, internally integrated 520KB RAM and onboard 8MB PSRAM, using SPI protocol communication, with a speed of up to 40M. USB:CH340X:Automatic download circuit,equipped with E8051 core compatible with MCS51 instruction set,with an average instruction speed 8-15 times faster than standard MCS51.ESP32-CAM module uses CH340X to implement automatic download circuit,and with USB,it is easy to write and debug ESP32. CMOS:OV5640 Camera:Provides the complete functionality of a single-chip JXGA(1632x1232) camera and image processor,offering multiple formats of full frame sampling,scaling,or windowing 8-bit/10 bit images through the serial camera control bus(SCCB) interface,with an optimal image distance of 20-250cm. Dual power supply mode:USB and external battery:reserved battery welding points,default does not include battery,users can connect 3.7V lithium-ion battery by themselves.The module is equipped with IP5306 power management chip to detect battery level/charging status.In battery power supply mode,double-click reset button to turn off the device,and click reset button to turn on the device. flash Card:Supports up to 32GB of storage card Sensor Category:Optical Sensor Working current:0.15A Working voltage:5V Size:48mm x 30mm Module application scenarios: Secondary development of Aolt applications such as monitoring,video,and p ography Low cost camera solution for IoT node devices Colour:As shown Material:PCB Package Contents: 1 x development board 1 x OV5640 Camera 1 x radiating rib Only the above package content, other products are not included.
