A placa Kitronik Halo HD para BBC micro:bit incorpora 60 LEDs ZIP coloridos individualmente endereçáveis. Divide também P1 e P2 num tamanho padrão de 0,1”, possui um microfone MEMS para deteção de som e uma campainha piezoelétrica para reproduzir som. Se isto não for suficiente, também possui um relógio de tempo real (RTC) integrado controlado por linhas I2C do microbit. A placa possui ainda dois orifícios de montagem M3. Pensamos que concordará, o quadro está repleto de recursos úteis.

No tools required, not even a screwdriver, plug the micro:bit, available separately, straight into the onboard edge connector and you are good to go!
The board has a 3xAA battery holder mounted on the rear, with a power switch on the front of the board. A regulated supply is produced on the board which is fed into the 3V and GND connections to power the connected BBC micro:bit, removing the need to power the BBC micro:bit separately. See the Datasheet for more information.
Kitronik have created custom blocks for the Halo HD for use with MakeCode. To add these blocks, first go to makecode.microbit.org and start a new project. Under the “Advanced” section click on “Extensions”. In the next window search for “Halo HD”. Then, click on the tile to import it into MakeCode. You will see that the blocks are split across three categories; ZIP LEDs, Microphone and Clock. You can find more information on the MakeCode editor and also on how to write code for it with MicroPython in the Datasheet.
To get you off to a flying start we have produced a number of code examples that cover all of the onboard features and that will also serve to inspire your own projects. You will find links to these examples in the resources section below.
