Spresense combines multi-core and power efficiency
Spresense is 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.

A wide range of use cases
The Spresense development board is designed to be very versatile and can be used for a diverse set of implementation areas such as imaging, logistics, AI, robotics, audio, security, production and more where battery life and CPU power are key.
Professional development using the Arduino IDE or the Spresense SDK
Developers can create solutions with Spresense using the Arduino IDE or the NuttX based Spresense SDK which provides a more extended API. 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, the Spresense Extension board makes the Spresense development board compatible with selected Arduino shields.
External software development environments
MicroEJ provides a suite of software tools that enables developers to program Spresense using Java.
Zerynth provides developers with an ecosystem of software tools to program Spresense in Python.
Hardware extension options
Spresense ext. board
The Spresense extension board provides pin compatibility with selected Arduino shields along with an SD card slot, a headphone jack and multiple microphone pins.
Spresense camera board
The Spresense camera board features a Sony 5 Mpixel image sensor with an onboard encoder for pictures in JPEG, RAW, Y/C or RGB format. It connects directly to the main board through a dedicated parallel interface.
BLE add-on
This add-on adds Bluetooth LE communication function to Spresense. Built-in antenna, TELEC, FCC, CE, IC Radio Law certification has been acquired, so it can be used immediately as a wireless device combined with Spresense.
Sensor add-on
This sensor add-on provides acceleration, pressure and geomagnetism data which are indispensable for motion sensing. Additionally, it can as be extended with more than 7 sensor functions such as illuminance and proximity.
Powered by Sony's CXD5602 microcontroller
Despites its compact footprint of only 6.5 x 6.5 mm, 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 dependant use cases. The CXD5602 microcontroller is available for volume orders in case your company is interested in developing your customized PCB solution.
