Building on SONY's extensive experience of mobile phone technology, Spresense is a compact development board based on their power-efficient multi-core microcontroller CXD5602. It allows developers to create IoT applications in a very short time and is supported by the Arduino IDE as well as the more advanced NuttX based SDK. Spresense is equipped with a real-time clock, 8MB of Flash memory, GPS receiver and supports high-resolution audio codecs. The board allows for IoT versatility and can be developed for a vast range of uses, such as a drone utilizing the GPS and high-performance processor, a smart speaker utilizing high-resolution audio recording and playback as well as the built-in full-digital amplifier, or a low-power time-lapse camera utilizing the camera interface. This main board interfaces with the extension board which provides audio and digital I/O as well as an analog input and access to the microSD card slot. * CPU: ARM® Cortex®-M4F x 6 cores * Maximum clock frequency: 156MHz * SRAM: 1.5MB * Flash memory 8MB * Digital input / output: GPIO, SPI, I2C, UART, I2S * Analog input: 2-ch (0.7V range) * GNSS: GPS(L1-C/A), QZSS(L1-C/A), GLONASS(L1), WAAS, QZSS(L1-S) * Camera input: dedicated parallel interface * Size: 50mm x 20.6mm * Model name: CXD5602PWBMAIN1 Any questions?
