Compose a monophonic microbit musical masterpiece with the Kitronik :KLEF Piano for the BBC micro:bit. It features 15 capacitive touch pads, with 13 arranged as a single octave and 2 up down function buttons that can allow you to shift octaves.

:KLEF also features; an onboard amplifier circuit for extra 'more', an onboard speaker, and an onboard edge connector that the micro:bit slots into.

To use the Piano, the BBC micro:bit should be inserted firmly into the edge connector, either way around. If the Link Header is being used, the BBC micro:bit LED display should be facing the Piano keys. Kitronik has produced a MakeCode getting started guide which you can follow here.

Power is provided via a 5V micro USB connector. The board then produces a regulated 3.3V supply fed into the 3V and GND connections to power the connected BBC micro:bit, removing the need to power the BBC micro:bit separately. This also powers the capacitive touch sensor IC and audio amplifier.

The potential uses for the :KLEF Piano for the BBC micro:bit doesn't have to be just musical in nature. You can use the piano keys to transmit from the micro:bit attached to the board to other micro:bits over radio. And if that other microbit happened to be inserted into a :MOVE mini... Piano remote control! You can even take control of the :MOVE minis ZIP LEDs!

These 3.7V Polymer Lithium-Ion (LiPo) batteries provide a high power capacity in a very small lightweight package, making them ideal for many applications. They are often used in portable consumer products such as Bluetooth speakers and mobile phones. The batteries are supplied with 100mm leads terminated with a JST adapter cable.

These Polymer Lithium batteries come with a built-in protection circuit that protects against; overvoltage, over current, over-discharge and also provides short circuit protection. When fully charged the battery will have a voltage of around 4.2V and when fully discharged the battery has a cut off voltage of 2.4V.

These batteries do not have a hard protective case. You should take care when housing the batteries in your design to ensure they have sufficient mechanical protection to protect the battery from any possible damage. If a battery does become damaged (dented, bent, etc) then it should not be used. Lithium Polymer batteries require special charging circuits. Do not attempt to charge these with anything but a specialised Lithium Polymer charger.

Features:

Built-in protection circuit to prevent overcharging or discharging.

Built-in short circuit protection circuit.

Robust power source under extreme conditions (-10 to 60C).

Caution:

These batteries are capable of delivering high current output. If using conductive thread, a short in the circuit (between thread) could create sparks and heat. We recommend using coin cell holders and batteries for wearable projects.

When removing the connector from a socket do not pull it out using the connecting wires as this can damage the connector.

Neither the battery nor its protection circuit are waterproof, and if being used in an environment where water contact is possible or likely then the battery should be further protected.

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.
