The KS027 Arcade Aura 3 combines a 3-digit 1.5-inch red 7-segment display with 18 individually addressable RGB LEDs arranged around the border — all in a single board. Display scores, counters, or timers while the LEDs provide customisable lighting effects synced to game events.

The 7-segment display is controlled via a 24-bit shift register protocol (compatible with 74HC595-style chaining). Daisy-chaining multiple boards is as simple as clocking another 24 bits before latching — making it easy to drive a bank of score displays from a single MCU SPI bus.

The board is pin-compatible with some existing arcade game score displays, making it a direct drop-in replacement for popular arcade cabinets.
