Spresense combines multi-core and power efficiency.
Ideal for professional use cases on the edge
With its unique combination of solid computing ability and advanced power efficiency, Spresense is ideal for edge computing. In the use cases below, the Spresense board is featured in solutions where there is a need for sensor analysis, image processing and data filtering in which other microcontroller based alternatives fall short.
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.
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.
Wi-Fi add-on
iS110B is a Wi-Fi add-on board for Spresense. In compliance with IEEE802.11b / g / n (2.4GHz), it supports Wi-Fi Direct and WPS as well as access point mode and station mode. This product is already equipped with a chip antenna, so you can use it immediately.
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.
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.
neqto: is an embedded-MCU edge platform that remotely controls devices and sensors connected to Spresense and provides a mechanism for real-time, two-way data communication.
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.
