Spring Into STEMMA

Who doesn't look forward to spring? It improves on nearly every single thing winter has to offer. Sunshine? Check. Warm breezes? Check. People's general mood? Check. Blasting your favorite feel-good playlist (Paul Simon's April She Will Come, Here Comes the Sun by the Beatles, Nina Simone's Spring Is Here ...to name a few)? Check. Opening up the workshop doors and bringing your projects into the daylight? Check. Plants, plants, and more plants? Check. Check. Check. 

That's where STEMMA comes into play. See below for some of our fave STEMMA products and projects, with some spring-focused learn guides to get you started. 

WHAT IS STEMMA? STEMMA is a plug-and-play board and sensor system that lets you quickly plug together various devices and accessories, without any soldering! STEMMA uses 3-pin cables for simple analog and digital devices, like relays and buttons. For more complex sensors and displays, we use a 4-wire I2C connection. For larger boards and devices we use a Grove-compatible connector, for smaller ones we use a Qwiic-compatible connector called STEMMA QT. Check out all of our STEMMA cables and connectors here - make sure to read the product descriptions in full before deciding which ones you'll need.
