The ACCESS:bit is a bolt-on/clip-on board for the BBC micro:bit that simulates an access barrier. It includes a servo-driven barrier arm, an integrated 3×AAA battery cage with on/off switch, and a buzzer for sound effects. The ACCESS:bit joins the Kitronik family of transportation micro:bit accessories alongside the STOP:bit and LAMP:bit.

Once the micro:bit is fitted, its LED matrix remains fully visible and can display warning signals, stop/go symbols, or act as a light sensor for autonomous barrier actions. The board connects via the supplied M3 countersunk screws or crocodile clips.
