Add some color to your projects!  

These LEDs allow you to color mix any color by varying individual red, green and blue LED chips inside. These are CA (Common Anode) LEDs, which means you connect common anode pin to 3.3 or 5V and the other pins to ground (or GPIO pin) through a resistor. 

  • Red - 2.0 - 2.2V forward voltage, 20 mA current
  • Green - 3.0 - 3.2V 
  • Blue - 3.0 - 3.2V 

If connecting to GPIO pin, remember that the logic is reversed - turning pin LOW turns ON the specified LED and turning the pin HIGH turns OFF the LED color. Use PWM to set the intensity of each LED to do color mixing. 

These are clear LEDs, allowing you to see the individual colors. If you want to diffuse the LED for better color mixing, you can just sand it lightly with a nail file or sandpaper to cloud it. 

This can be used in the ProtoStax Micro Servo Analog Gauge Add-On to add color-indication for the analog gauge (for example, you can have different scales at different colors and use the LED to indicate which scale's reading is being displayed). 

This comes with a plastic LED holder so you can attach the LED to top plate of the ProtoStax Micro Servo Analog Gauge Add-On!

ProtoStax Enclosures are Stackable, Modular & Extensible

They ease your path from Prototype to Product! Make your prototypes useable and attractive with ProtoStax!

  • ProtoStax Enclosure / Case in Platform Configuration showing Arduino. Pre-drilled and threaded mounting holes make assembly easy and convenient. Acrylic risers elevate board off the surface for improved airflow

    Use it as a prototyping plate, with full and open access to your device while prototyping. Rubber feet protect your board and your table top! 

  • ProtoStax Enclosure / Case in Open Configuration showing Arduino

    Omit the side walls and just add the top for an open configuration with more airflow and open access. 

  • ProtoStax Enclosure / Case in Fully Closed Configuration showing Arduino

    Add side walls and the top to form a fully enclosed case for maximum protection. 

    The cases offer connectivity to external systems using our unique cable management methods (see features above)


Extension kits and Add-Ons allow you to add functionality to your enclosure. Add a fan or two, switches, camera & tripod mount, and more!

Just filter by "extension kit" or "add-on" in the main shopping page to view the choices, or click below!

All ProtoStax cases are compatible with each other and can be stacked side-by-side (horizontally) or one on top of the other (vertically). Mix-and-match multiple ProtoStax cases and put together a larger enclosure from the individual ones! Our Raspberry Pi + Breadboard, or Raspberry Pi + Arduino enclosures are popular bundles. You can also mix-and-match various Raspberry Pi enclosures (A+, B/B+, Zero enclosures to build your hybrid cluster with whatever Pis you have lying around!)
