The Spresense development board removes the effort in developing high quality IoT solutions.
Spresense is a compact development board based on Sony's power-efficient multicore 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 SKD.
Developers can create soluions with Spresense using the Arduino IDE or the NuttX based Spresense SDK which provides a more extended API. Depending on the requirement for each product, 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. This makes Spresense a very versatile IoT board that can be used for a very diverse set of implementation areas such as imaging, logistics, AI, robotics, audio, security, production and more where battery life and CPU power are key.
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 dependant use cases.
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 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.
