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. This mainboard includes both the Sony CXD5247GF and the CXD5602GG processor chips and includes an onboard GPS chip antenna, a camera interface, USB based 0debug interface and a 26 pin extension connector. Several add-ons can be made or purchased to support additional features like LTE, WiFi, Bluetooth BT/BTE and image sensors.
- 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.
