This board is a low-power 2.4GHz BT beacon breakout built around the InPlay IN100 NanoBeacon. It is designed for fast deployment in wireless sensor monitoring, asset tracking, retail beaconing and real-time location tag projects where long field life and minimal programming are priorities.

Power can be supplied from a single 3V coin cell, with a 12mm CR1225 battery holder fitted to the board. A vertical Qwiic connector is included for easy integration with the Qwiic ecosystem, while the UART interface is broken out to 0.1-inch spaced through-hole pins for use with a Serial Basic.

The board also breaks out four GPIO pins, GPIO 4-7, plus the two I/O power switch pins, SW0 and SW1. This version has male headers pre-soldered to the through-hole pins and omits the power LED and reset button for applications that need minimal assembly or modification.

The InPlay NanoBeacon Config Tool provides a GUI for configuring advertising, pairing and data packet behaviour without tricky firmware work. Take care with the Config Tool's “Burn/Program” option: it uploads the settings and locks the module, and cannot be undone. The “Run in RAM” test mode is available for many settings, but I2C is not available in RAM testing mode.

Jargon buster

Plain-language definitions for the technical terms used above.

breakout: A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
CR1225: CR1225 is a specific size of 3 V coin cell battery, about 12 mm wide and 2.5 mm thick. Checking this code matters because coin cell holders only fit certain battery sizes, and battery capacity affects how long a beacon can run.
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 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.
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 is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
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 is temporary memory used while a device is running, and its contents are lost when power is removed. A “Run in RAM” mode is useful for testing settings without permanently programming the module, but it may not support every feature.
UART: UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
