README ====== 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, 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.
