Jargon buster
Plain-language definitions for the technical terms used above.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- 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.
- Terminal block
- A connector used to join wires together in a neat, removable, or serviceable way. For this product, it helps split one power input into several outputs without soldering.
