ZIP Halo HD For The BBC Micro:bit

The Kitronik Halo HD board for the

BBC micro:bit

incorporates 60 individually addressable full colour ZIP LEDs. It also breaks out P1 and P2 to a standard 0.1 footprint, it features a MEMS microphone for detection of sound, and a piezo buzzer to play sound.

We also stock the standard

24 LED Zip Halo

.

If that wasn’t enough, it also features an onboard real time clock (RTC) controlled by I2C lines from the

microbit

. The board also has two M3 mounting holes. We think you’ll agree, the board is loaded with useful features. It doesn’t stop there…

Plug n Play: 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!

Onboard Power: 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.

MakeCode Blocks: 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

.

Examples: 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.
