ProtoStax Micro Servo Analog Gauge Add-On
Out of stock
Couldn't load pickup availability
Add a micro-servo to your ProtoStax Enclosure! This Add-On consists of a top plate with a cut-out to fit micro-servos like the SG90, SG92R and Futaba micro-servos, as well as a cutout to fit a 5mm LED with plastic holder (We have a common-anode RGB LED with plastic holder that will fit in this hole - add separately)
Swap out the top plate of your existing ProtoStax Enclosure with the corresponding unit from this kit. ProtoStax Enclosure not included - you need to get that if you don't already have it.
We also have a ProtoStax Analog Gauge Needle Horn for Micro Servo - 2F 21 Teeth (add separately) that will fit the micro-servo and can be used to complete your Analog Gauge.
We also have card-stock color gauge scales for
- Air Quality Index
- Temperature, Humidity and Pressure
for purchase, that will fit your ProtoStax Enclosure Top plate. You can design and print your own too, of course!
This Add-On does not include the Enclosure. Make sure to add a ProtoStax Enclosure to your order if you don't already have it!

Getting Started w/ ProtoStax Enclosures
See how to set up & use ProtoStax enclosures for your next DIY Electronics/Computing project with Arduino, Raspberry Pi & other MCUs & SBCs
ProtoStax Enclosures are Stackable, Modular & Extensible
They ease your path from Prototype to Product! Make your prototypes useable and attractive with ProtoStax!
Modular
-
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!
-
Omit the side walls and just add the top for an open configuration with more airflow and open access.
-
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)
Extensible
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!
Stackable
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!)
