Inside your Peripherals Kit you have a micro:bit connection device called the octopus:bit.


The octopus:bit allows you to attach peripherals to a micro:bit’s input / output pins using color-coded positions.


Connect to a Micro:bit

The micro:bit gets inserted into the octopus:bit as shown here:


The micro:bit buttons should be facing toward you when looking at the front of the octopus:bit.

The red PWR LED, on the right-hand side of the octopus:bit, will light up when the micro:bit is inserted correctly.

Connect Peripherals

The octopus:bit makes connecting peripherals easy!


There are a few things to know:

  1. The colors on the cables matter.

  • Black is G (Ground) and needs to be connected to a black pin

  • Red is VCC (Power) and needs to be connected to a red pin

  • Yellow is S (Signal) and can be connected to a yellow or blue pin

  1. The two ends of the cable are different

  • The larger end is inserted in the peripheral and should lock into place

  • The smaller end attaches to the octopus:bit

Input / Output Pin Diagram

This diagram shows the micro:bit functions and capabilities of each of the octopus:bit pins.

  • The green ~ symbol means the position can be used as an analog input.

  • P0, P1, and P2 have no shared micro:bit functions.

  • All positions can be used as digital inputs / outputs.

Output Voltage Switch

The octopus:bit has a VCC Switch that allows you to switch the BLUE connector positions between 3.3 Volt and 5 Volt operation.
