Spresense Main Board - CXD5602 Microcomputer for IoT Application

Description
Spresense is a compact development board based on Sony¡¯s power-efficient multicore 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.
Integrated GPS - The embedded GNSS with support for GPS, QZSS, and GLONASS enables applications where tracking is required.
Hi-res audio output and multi-mic inputs - Advanced 192kHz/24 bit audio codec and amplifier for audio output, and support for up to 8 mic input channels.
Multicore microcontroller - Spresense is powered by Sonys CXD5602 microcontroller (ARM Cortex -M4F ¡Á 6 cores), with a clock speed of 156 MHz.
