Spresense - made for IoT development
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 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 Sony's CXD5602 microcontroller (ARM® Cortex®-M4F × 6 cores), with a clock speed of 156 MHz.

Spresense Software
Spresense provides two software development environments.
・Development environment using the Spresense Arduino Library
By selecting to use the Spresense Arduino Library software development can be undertaken relatively easily using Arduino IDE, which will be familiar to many developers.
For those who would like to develop software using Spresense Arduino Library, please refer to following chapters.
Spresense Arduino Library Getting Started Guide and Spresense Arduino Library Developer Guide

・Development environment using the Spresense SDK
The Spresense SDK is Sony’s original development environment. It based on the build environment, GNU Make, provided by NuttX. This provides a low level API, allowing users to maximizing the performance of a Spresense based system, such as optimizing memory use, power saving, control of multicore processing, etc.
If you would like to try developing software immediately using the Spresense SDK, please refer to following chapters.
