Qwiic, or STEMMA QT , is a very efficient way to quickly prototype an idea, but a lot of Qwiic/Stemma QT driver boards only have one port, and devices have two ports but that's only good for chaining. This Multiport board allows boards that have only one Stemma QT/Qwiic port to be added to the I2C bus. Or, use this hub to add as many I2C devices to the bus as you need. Complete with mounting holes so the board can be added to any system....

Take a deep breath in...now slowly breathe out. Mmm isn't it wonderful? All that air around us, which we bring into our lungs, extracts oxygen from, and then breathe out carbon dioxide. CO2 is essential for life on this planet we call Earth - we and plants take turns using and emitting CO2 in an elegant symbiosis. But it's important to keep that CO2 balanced - you don't want too much around, not good for humans and not good for our...

Circuit boards power the world but are built for hard goods. LOOMIA makes a new form-factor of circuit—a soft circuit (e-textile) system—that can be used to power soft goods. From automotive to apparel, our soft circuit systems can be used when standard PCBs (Printed Circuit Boards) aren't up to the task—bringing heating, lighting, and sensing to car seats, medical apparel, outdoor gear, and more.

Power over Ethernet (PoE) splitters can make your project wiring a breeze - and best of all they work to connect any 802.3af-capable router to any Ethernet device,  even if it doesn't natively support PoE!  The splitter takes a unified PoE signal (data and power) from one RJ-45 cable, and then separates the data (Ethernet) and power (5 VDC regulated) into two different lines for non-PoE devices. This is an...

If you want to do more with the BBC micro:bit, getting those pins from the card-edge connector is going to be your first hurdle. Unlike many dev-boards, the micro:bit isn't breadboard-friendly. That makes the 'bit durable and easy to manufacture but means you need a special connector. This surface-mount edge connector is very slim and fully SMT, so it's a breeze to automate. It also only has contacts on one side, just like the...
