SparkFun Qwiic micro:bit Breakout

The SparkFun Qwiic micro:bit Breakout is a board that connects to the BBC micro:bit and expands the capabilities of the development platform by providing access to more pins and allowing for connections to the I2C and SPI buses. This breakout board for the micro:bit’s edge connector allows intermediate and advanced users to connect the micro:bit to breadboards and other Qwiic sensors, motors, LEDs and more.

The micro:bit on its own has three digital/analog input/output rings available for you to use initially with alligator clips. With the micro:bit Breakout we have broken out all 21 GPIO, power and ground-to-pin outs in a 0.1" formation and with two individual Qwiic Connectors. With this breakout you will be able to unlock the full potential of your micro:bit!

Note: No micro:bit or headers are included with this breakout; they will need to be purchased separately. If you would like a micro:bit breakout with headers already soldered on, be sure to check out this board's sibling.


The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

Wireless Remote Weather Station with micro:bit

May 11, 2020

Monitor the weather without being exposed to it through wireless communication between two micro:bits using the radio blocks! This is useful if your weather station is installed in a location that is difficult to retrieve data from the OpenLog. We will also explore a few different ways to send and receive data.

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.
See all skill levels


Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
