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. If that weren't enough, it also features an onboard real time clock (RTC) controlled by I2C lines from the micro:bit. The board also has two M3 mounting holes. We think you'll agree, the board is loaded with useful features. Please Note: BBC micro:bit is NOT included.
