The cyber:bot board is very similar to the Board of Education or Board of Education Shield. It fits on top of the same small robot chassis. It has 3-pin headers with selective voltage, and a 3-position switch for powering the breadboard circuits with or without powering the servos.
What is new is that this robot has more than one "brain." Your Python programs for a micro:bit mounted on the cyber:bot board will communicate with a pre-programmed Propeller multicore microcontroller "assistant" on the bottom of the board. The Propeller automatically controls the servo motors, interacts with sensor circuits, and replies back with data.
For a more complete reference, see the cyber:bot board guide.
