BBC's Micro:bit is a lovely little platform to power simple yet clever projects.

You can use the two real-life, physical buttons and display information using the LED grid only.

But you can achieve more if you plug external peripherals, like servos, speakers. Micro:bit boards offer two connectors for external 3V power and ground. And three connectors to connect whatever you want to it to interact with your program.

And my design starts here: how do you easily connect external devices to the board, without having to permanently dedicate the board to one project? That is without soldering wires directly on the board or having wobbly alligator clips connected to it.

What you will get: a cradle to connect your micro:bit board to 5 wires available for every project you have in mind. The cradle is permanently connected to the wires. Your micro:bit board simply slides in and out to benefit from the connectors.

What you need:

• PLA
• brads (brass paper fasteners)
• small color wires for electronics
• soldering iron and wire

Brads

Solder a colored wire to the head. It is very easily done. Copper brads heads are large and stick perfectly to the solder.

Insert the leg of the brad in one of the five slits. With a small and pointy tool, help the tip of the leg curl up as it gets out. Your goal is to have the head of the brad fit in its slot and the leg to be curled over the edge. With the pictures. Ask me in the comments if you need.

One you have repeated the operation with all the brads, you are done.
