U037

Fish-eye Camera Module (OV2640) SKU: U037 M5CameraF is a development board for image recognition. It features an ESP32(4M Flash + 520K RAM) chip and 2-Megapixel carmera(OV2640).M5CameraF offers plenty of storage, with an extra 4 Mbyte PSRAM. It also supports image transmission via Wi-Fi and debuging through USB Type-C port. The hardware comes preloaded software, programmed by ESP-IDF. It is an application to run Wi-Fi camera. The output image is size 600*800, since it’s 2-Maga camera, you sure can optimize the software to output the maximum size of photos. what this software can do? • • • • Power the board via USB type-C or GROVE Use your phone to Wi-Fi scan an AP name start with ‘m5stack-‘ and click to connect this AP. Open up web browser on your phone and visit 192.168.4.1 Then here comes the picture. Video is about 5-6 frames per senconds. not super fast. The hardware also comes with some reserved weld pad, just in case you want put these chips back on board. • • • • 9-axis gyroscope (MPU6050) pressure sensor (BME280) Digital silicon microphone (SPM1423) Lipo Battery power pins Feature • • • • • • • ESP32 specifications o Dual-core Tensilica LX6 microprocessor o Up to 240MHz clock frequency o 4MB PSRAM o 4MB Flash memory o Integrated 802.11 BGN WiFi transceiver o Integrated dual-mode Bluetooth (classic and BLE) o Hardware accelerated encryption (AES, SHA2, ECC, RSA-4096) CP2104 USB-to-TTL converter ESP32-WROVER (PCB Antenna) OV2640 sensor o Output Formats(8-bit): ▪ YUV(422/420)/YCbCr422 ▪ RGB565/555 ▪ 8-bit compressed data ▪ 8-/10-bit Raw RGB data o Maximum Image Transfer Rate according to specific format ▪ UXGA/SXGA: 15fps ▪ SVGA: 30fps ▪ CIF: 60fps o Scan Mode: Progressive Camera specifications o Field of View : 160 degree o Maxmium Pixel: 2-Mega Sensor best resolution: 1600 * 1200 Size：23.5 × 48 × 23.5mm Include • • • • 1x M5CameraF 1x LEGO Adapter 1x Wall/1515 1x Type-C USB(20cm) PinMap Camera Interface PinMap Interface Camera Pin M5CameraF SCCB Clock SIOC IO23 SCCB Data SIOD IO22 System Clock XCLK IO27 Vertical Sync VSYNC IO25 Interface Camera Pin M5CameraF Horizontal Reference HREF IO26 Pixel Clock PCLK IO21 Pixel Data Bit 0 D2 IO32 Pixel Data Bit 1 D3 IO35 Pixel Data Bit 2 D4 IO34 Pixel Data Bit 3 D5 IO5 Pixel Data Bit 4 D6 IO39 Pixel Data Bit 5 D7 IO18 Pixel Data Bit 6 D8 IO36 Pixel Data Bit 7 D9 IO19 Camera Reset RESET IO15 Camera Power Down PWDN see Note 1 Interface Camera Pin M5CameraF Power Supply 3.3V 3V3 3V3 Ground GND GND GROVE Interface Grove M5CameraF SCL IO13 SDA IO4 5V 5V GND GND LED Interface LED M5CameraF LED_Pin IO14 The following tables are Reserved Chip Interfaces BME280 Interface It’s IIC address is 0x76.
