Add a HC-SR04 Ultrasonic Sensor to your ProtoStax Enclosure with this Extension Kit. 

The kit comes with a Short Side wall piece with mounting holes and cutout for the HC-SR04 Ultrasonic Sensor, along with PCB spacers, M1.2 mounting screws and nuts (these tiny screws and nuts will fit most types of HC-SR04 sensors - please ensure the size of the mounting hole on your sensor!). You can also just use some double sided tape to attach the sensor to the Short Side wall piece.

** This DOES NOT include the HC-SR04 sensor. **

**ProtoStax Enclosure not included - you need to get that if you don't already have it. **

This kit will work with any ProtoStax Enclosure - Arduino, Raspberry Pi or Breadboard/Custom, so you can the HC-SR04 to any of these. 

Simply replace the existing Short Side wall of your enclosure with the one from this kit, with your HC-SR04 sensor mounted on the piece. Voila! 


This Extension Kit does not include the Enclosure. Make sure to add a ProtoStax Enclosure to your order if you don't already have it!

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!

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!)
