My son has just received a Kitronik ZIP Halo HD for micro:bit.
When he first ran the sample code all 60 LEDs in the ring worked. He did a few simple things like changing the colours in response to button presses, but now only the first 12 of 60 LED light up.
When the Zip Halo HD is first turned on a few of the LED around the ring briefly flash green, but when the program runs only the first 12 LEDs illuminate regardless of what colour is set.
I’ve done basic trouble shooting like re-flashing the micro:bit with the sample code, testing different colours, disconnecting and reconnecting everything, using different power supplies, and checking that the micro:bit has the latest firmware (0249).
Can anyone suggest further trouble shooting steps? Does this sound like a hardware issue (e.g. bad contact/trace/joint)?
