IN100 NanoBeacon Lite Board

Jargon buster

Plain-language definitions for the technical terms used above.

Bluetooth beacon

A Bluetooth beacon is a device that repeatedly broadcasts a small wireless signal so nearby phones, receivers, or gateways can detect its presence. It is useful for proximity, tracking, and simple location projects, but it is not the same as a full two-way Bluetooth data connection.

breakout

A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.

CR1225

CR1225 is a specific size of 3 V lithium coin cell, about 12 mm in diameter and 2.5 mm thick. The code matters because a coin-cell holder only fits one size, and a cell's capacity affects how long any device it powers can run before the battery needs replacing.

Eddystone

Eddystone is a Bluetooth beacon format originally defined by Google for broadcasting identifiers or small pieces of data. Support for Eddystone matters if your project needs to work with software or receivers that expect that beacon format.

GPIO

General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.

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.

I2C

I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.

iBeacon

iBeacon is Apple’s Bluetooth beacon format for broadcasting an identifier that nearby devices can recognise. Support for iBeacon matters when building proximity or location projects that need compatibility with apps or systems using that format.

IN100 NanoBeacon

A small Bluetooth beacon module from InPlay that can be configured to broadcast short wireless messages. The exact module matters because it determines the supported beacon modes, power use, and configuration tools you can use.

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.

Qwiic

Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.

RAM

RAM (random-access memory) is fast, temporary memory a device uses for working data while it is running; in its common volatile form, its contents are lost when power is removed. Some devices offer a mode that applies settings to RAM only, which is handy for testing changes temporarily because they are not stored permanently and disappear at power-off.

through-hole

A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.

UART

UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
