Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- alligator clip
- An alligator clip is a spring-loaded metal clip used to make temporary electrical connections to wires, terminals or test points. It is useful for quick bench testing, but it is less secure than a screw terminal or locking connector.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- conductive thread
- Thread made with metal or other conductive fibres so it can carry electricity while being sewn into fabric. It matters for wearable and textile projects because it can replace wire, but it has more resistance than normal hookup wire.
- LiPo
- A lithium polymer rechargeable battery commonly used in portable electronics projects. It matters because LiPo batteries need correct charging circuitry and care, and this board includes hardware intended for that battery type.
- native USB
- Native USB means the microcontroller itself handles USB communication, rather than using a separate USB-to-serial chip. This matters for programming, debugging, and projects that need the board to act directly as a USB device.
- photoresistor
- A light-sensitive resistor whose resistance changes depending on how much light hits it. It matters for projects such as night-lights and light alarms because it gives a simple way for a microcontroller to sense brightness.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
- Thread
- A low-power wireless mesh networking standard designed for smart home and IoT devices. It matters because Thread devices can relay messages through each other, helping build reliable networks for sensors and controllers.
