The last of the bunch… XL features 4 leds per segment. It’s exactly the same as the standard one just with 4 leds per segment. It’s built exactly the same way, so refer to documentation on the original thing/SE edition (video build).
No feet supplied, I suggest using the integrated wall hook. Have not tested mounting feet from the original thing, can’t tell for sure if they keep it in balance.
Important: As can be seen in my instructions for other things I usually connect a regulated 5V power supply to the led strip and then connect an arduino to the led strip using its 5v pin. This is absolutely within specs as stated in the documentation for pro mini/nano.
Power per module is limited to 200mA because some people connect usb to their arduino and then power the leds using the 5v pin. The Arduino will keep resetting if you draw too much current from the 5v pin!
You should raise the limit to at least 500mA per module to get a noticeable difference between the three brightness settings. So make sure you’re powering it properly.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
