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.
The Spresense main board 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.
The 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.
The Spresense extension board provides pin-compatibility with selected Arduino shields along with an SD card slot, a headphone jack and multiple microphone pins.
The Neon case is a rugged, self-assembly enclosure for the Sony Spresense main and extension boards. The case is made from 8 sheets of material that have been especially cut to support and protect the boards, while leaving the connectors easily accessible.
