Jargon buster

Plain-language definitions for the technical terms used above.

IPS

IPS is a type of LCD panel that keeps colours and contrast more consistent when viewed from an angle. This matters for small displays that may be mounted in a dashboard, handheld project, or enclosure where the viewer is not always looking straight on.

LCD

LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.

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.

reverse polarity protection

A circuit feature that helps protect the board if power is connected the wrong way around. It matters because it can reduce the chance of damaging the breakout during wiring mistakes, especially in classroom or prototyping use.

RGB

Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.

RP2040

The RP2040 is a dual-core Arm Cortex-M0+ microcontroller chip from Raspberry Pi, used on many maker boards and offering programmable I/O, multiple GPIO pins and reasonable processing speed. Code and accessories built for that chip should work where RP2040 compatibility is listed, though demanding tasks such as reading a camera can require careful pin allocation and timing.
