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 SDK.
Integrated GPS - The embedded GNSS with support for GPS 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.
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.
