Expansion headers allow users to further extend the rich native features by adding Arduino shields or any of a selection of specially developed add-on boards.

These include the Spresense-BLE-EVK-701 Bluetooth Low Energy board and the Spresense -Sensor-EVK-701 containing a MEMS accelerometer, barometer, and magnetometer. Spresense is compatible with the Arduino development environment (IDE), and comes with a set of extended APIs that give developers the additional option to use the advanced NuttX based software development kit (SDK).
The CXD5602 SoC on the main board contains six 156MHz ARM Cortex-M4F cores, ensuring generous compute performance and low latency. Peripherals include an 8-bit parallel camera interface, a multi-constellation GNSS receiver, and a sensor-fusion block to simplify movement or context sensing using a combination of external MEMS accelerometer, eCompass, gyroscope, or pressure sensor. The CXD5247 adds a class-D Bridge-Tied Load (BTL) audio amplifier, 8-channel digital microphone and 4-channel analogue microphone inputs, as well as DC/DC converters and a low-dropout (LDO) regulator to provide the system power rails. Battery-charging and fuel-gauge peripherals further simplify the design of self-powered, connected, smart objects.
With its multicore compute engine and built-in GPS, Spresense is suitable for next-generation drones. Support for high-resolution audio recording and playback, and the full digital amplifier, create a perfect platform for new and more powerful smart speakers.
