Hardware Assembly
Attach Headers
If you have the version of the breakout board without headers, solder some breakaway headers to the board. You can also solder wire directly to the breakout.
Build Example Circuit
Note: The micro:bit must be facing up in order to make electrical connections to the pins.
To begin, let's light up an RGB LED. Attach the micro:bit to the breakout board, place the breakout board onto a breadboard, and connect an RGB LED through 330 Ω resistors. Use the image below to aid you in wire up the circuit.
Remember, LEDs are polarized parts and can only work properly in one orientation. The longest leg of the LED goes where the black GND wire is in the circuit.
