Sony Spresense Main Board

SPRESENSE is a low-power board computer for the IoT that is equipped with a 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. SPRESENSE will make the IoT smarter and more efficient.

Here's a compact development board based on Sony’s power-efficient multicore microcontroller CXD5602. It allows developers to create 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 Sony's CXD5602 microcontroller (ARM® Cortex®-M4F × 6 cores), with a clock speed of 156 MHz.

Despite its compact footprint of only 6.5 x 6.5mm, Sony's CXD5602 microcontroller runs 6 ARM Cortex-M4F cores with a clock speed of up to 156MHz and has an integrated GPS. Thanks to the FD-SOI (Fully Depleted Silicon On Insulator) production process, the CXD5602 chip is very power efficient which enables battery-dependent use cases.
