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...

PB86 Step Switch Breadboard-Friendly Breakout PCB - Pack of 12

Product ID: 5631

A couple of months ago we started carrying packs of colorful step switches reminiscent of the 16-step sequencer keys on TR-808 synthesizers. We gave folks the heads up that the switches are not breadboard or perf-board friendly i.e. would need to either be hand-wired or designed into a PCB. And then we heard LCD Soundsystem is coming back on tour - so we sold our...
