Kitronik Audio Cable for the BBC micro:bit

Add some colour to your next coding project with our new Halo board for the BBC micro:bit. The Halo has 24 ZIP LEDs, which are individually addressable full-colour LEDs. This means that each LED can display a huge spectrum of colours, allowing amazing colourful effects to be achieved.

The Halo bolts directly onto the BBC micro:bit using five bolts which are secure and robust. The board also has extension connector pads (0.1” pitch) allowing more ZIP LEDs to be connected. The P1 and P2 micro:bit pins are also broken out to 0.1" pads along with power and GND. This allows for additional connections to low power components such as sensors and switches.

The Halo takes a supply voltage of 3.5V-5V and provides a regulated power supply to BBC micro:bit. Power can be connected using the JST input using a 3xAAA battery holder, LiPo battery, or JST lead. Alternatively, you can solder a power supply directly to the solder pads on the PCB. The LEDs used are based on the WS2812B part which is compatible with any WS2812B driver code. They can also be coded in the MakeCode Block/Javascript editor.

Features:

Halo has 24 individually addressable ZIP LEDs.

Compatible with Adafruit NeoPixel and other WS2812B driver code.

Supply voltage: 3.5V to 5V.

The Clippable Detector board for the BBC micro:bit detects light, objects and can follow lines. The board is compatible directly with the BBC micro:bit and certain Kitronik boards, such as the Klip Motor Board.

The board works by using phototransistors to detect the reflectiveness of different surfaces. The Clippable Detector board has 3 phototransistor sensors evenly spaced out from each other. The sensors provide an analogue voltage to the BBC microbit. Five connections are required for full operation. These connections match those on a BBC micro:bit and can be attached using either bolts or croc-clip leads.

Kitronik have produced a set of custom MakeCode blocks for the Clippable Detector board. To add them to the editor, select the cog icon in the top right of the editor. Then, select Extensions from the drop down menu and in the search bar type and enter Kitronik. Pick the tile from the list and the new blocks will be added to the menu in the editor. It is also possible to use MicroPython to write code for this board.

Features:

Use the board to detect light, objects or to follow lines.

The board is fitted with 3 phototransistors that detect the reflectiveness of different surfaces.

Connect the board directly to the micro:bit or connect using croc-clip leads.

Kitronik created custom MakeCode blocks to make the job of coding as easy as possible.

The STOP:bit for the BBC micro:bit is the ultimate upgrade for traffic light/pedestrian crossing projects. Not only does it make coding the project a breeze, but the board is also supplied pre-assembled so you don't even need to fire up the soldering iron. Love it or hate it, variations of the pedestrian crossing project have been around for decades. When I did mine, it was on a 6502 EMMA board and coded with Assembly and it also included a level crossing. Thankfully, tapping low-level programming languages into a hexadecimal keypad is now a thing of the past. The Kitronik STOP:bit is a purpose-built accessory that can only lead to a more enjoyable project with a nicer looking end result.

Version 3 is the newest version of our best selling Mono Amplifier Kit that can be used with any personal stereo equipment, including MP3 players, making it an ideal kit choice for an amplifier case design project.

It uses an NCP2890 audio amplifier IC which is pre-mounted on the underside of the board (see image below) and can output 1.0W of power. The NCP2890 is an audio power amplifier designed for portable communication device applications such as mobile phone applications and PDAs. The IC also features an onboard “Pop and Click” at startup and closedown Noise Protection Circuit.

The kit is supplied with a pre-built jack cable, an 8ohm 66mm speaker, and a AA battery pack and can run off any voltage from 2.2 to 5.5 Volts (Absolute Maximum 6V). For a full list of parts, see the Contents section below.

Previous versions of this amp included a PP3 power connection and were designed to operate around 9V, V3.0 has been designed for use with 2 x AA batteries. There are several advantages to using AA batteries over PP3, they include; AA batteries are much cheaper, more readily available and will also last significantly longer than PP3 batteries, anything up to ten times longer.

Features:

Great value electronic project kit.

Works with any stereo equipment, including computers, phones, and tablets that can accept the jack lead.
