These brilliant inventions are a blessing for makers designing or using boards with standard 2.1mm DC barrel jacks. We’ve got ‘em with a slide switch and a rocker switch!
Many devices opt against a proper power switch, for size or cost or other design reasons. So, you’re expected to unplug when not in use. But you want something a little fancier! These 2.1mm DC Power Jacks have the same PCB layout as classic non-switched jacks but has a li’l extra on top – a labeled switch!
The switch does exactly what you’d expect: plug in your power supply (up to 16 VDC, 3A) and switch power on and off. On and off! On and off all daayyy-o. You can clicky-clack to your maker heart’s delight! We swear we’re not pulling your lead–I mean, leg, this has a seriously satisfying clack.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
