Sony Spresense Main Board (China)

Sony Spresense Main Board is a compact, Arduino-compatible development board based on the Sony multicore CXD5602 Microcontroller. The Main Board can be operated alone or with the extension board. The Spresense Main Board enables developers to create applications in a very short time and is supported by the Arduino IDE or the NuttX based Spresense SDK which provides a more extended API. Depending on the requirement for each project, the main board can be equipped with optional add-on boards with extra features such as BLE, Camera Board, and accelerometer sensors.

The Spresense Development Board is designed to be very versatile and can be used for a diverse set of implementation areas such as imaging, logistics, AI, robotics, audio, security, production, and any IoT application where battery life and CPU power are key.

The CXD5602 MCU features embedded GNSS with support for GPS, QZSS, and GLONASS, which enables applications where tracking is required. The MCU also integrates advanced audio with a 192kHz/24 bit audio codec, an amplifier for audio output, and support for up to 8 mic input channels.
