Spresense Development OverviewSpresense Development Overview

Spresense SDK

The C-based Spresense SDK is open source and comes with full documentation, tutorials and sample projects. The SDK is based on the real-time OS NuttX which is similar to the Linux framework. Depending on the requirement for each project, the main board can be equipped with optional add-on boards with extra features such as BLE, camera board and accelerometer sensors.

Additionally, Spresense has also support for the Arduino IDE for quick prototyping and testing. The Spresense Extension board makes the Spresense development board compatible with selected Arduino shields.
