- Headers
-
Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering 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.
- LED
-
A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- LiPo
-
A LiPo (lithium polymer) battery is a rechargeable lithium battery widely used in portable projects because it is light and compact. LiPo cells need correct charging circuitry and careful handling to stay safe, so equipment that supports LiPo generally includes charging or protection hardware suited to that battery type.
- schottky
-
A Schottky diode is a type of diode with a low forward voltage drop and very fast switching. It matters when choosing parts for power protection, voltage regulation, or high-speed circuits because it wastes less power than many standard diodes but usually has higher reverse leakage and lower voltage ratings.
- Schottky diode
-
A diode type with a low forward voltage drop and fast switching behaviour. It is useful when you want less power loss or quicker response, such as in battery-powered circuits, switching supplies, or reverse-current protection.
- TOPS
-
TOPS means trillions of operations per second, often used to describe AI accelerator performance. It helps compare whether a computing module is suited to lightweight image recognition or more demanding neural-network workloads.
- USB-C
-
USB-C is a small, reversible USB connector that can carry power, data and, on some devices, video over a single cable. The same connector can range from charging only to high-speed data, so the functions a given port actually supports vary.
