Feature:1. The dual-camera development board is mainly used for MCU development and image acquisition.2. Combining two kinds of highpixel cameras on one board provides a lowcost image gathering.3. The USB interface directly downloads the program, and the secure digital memory card reads the picture file, which is more timesaving and efficient.4. Equipped with a 2.8in TFT touch screen with a multifunction adapter board, more convenient to access and export signals.5. Provide external 3.3V and 5V power supply, which can supply power to external devices or printed circuit board.Specification:Item Type: Development BoardMaterial: Synthetic CardboardPurpose: MCU development and image acquisitionMCU: STM32F103RCT6Power Supply: 5V DC power supply or USB power supplyDebug Port: JTAG/SWD Mode (JTAG is used in the case of multiplexed debugging pins), supports online download and simulationUSB Serial Download: Onboard CP2102 imported USB to serial downloader, can download HEX files directly, which is convenient to useE2ROM: Interface I2CCrystal Oscillator: 8M main chip clock, and RTC clock chipMemory Card Socket: MINISD card, SPI interface modeLCD Screen: 2.8in TFT touch screen with multi-function adapter boardUSB Interface: One is USB to serial port, the other is USB communication portCamera: OV7670 camera with FIFO + 200W pixel OV2640 camera moduleChip IO Lead Interface: All IO leads, easy to useExternal Power Supply Interface: Provide external 3.3V and 5V power supply, which can supply power to external devices or PCB boardsButtons: One reset button and two customer buttonsBOOT Jumper: used when downloading and program runningLED Light: 3Pcs, can realize frame signal indication and marquee and other functions.Package List:1 x Development Board1 x USB Data Cable
