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. The Spresense Extension Board has the following connectors in addition to Arduino Uno compatible pin sockets:
- 3.5 mm headphone jack
- MicroSD card (not included, but we carry 'em in the store)
- Extra USB port
- Multiple microphone pins
The Spresense main board and extension board are connected by a Board-to-Board (B-2-B) connector.
Note: This is just the extension board. You'll need the main board as well.
Jargon buster
Plain-language definitions for the technical terms used above.
- IDE
- Short for Integrated Development Environment, a program used to write, run and manage code. It matters because some learners prefer a traditional coding workspace instead of a guided notebook-style lesson.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- microSD card
- A microSD card is a small removable flash memory card used to store data such as audio, images, logs or program files. Its capacity and formatting (often FAT32 or exFAT) affect how much can be stored and whether the card needs preparing before use.
