Product Description

NOTE: All anodized finishes except for black have a minimum purchase quantity of 30 units.

Proto Armour for Raspberry Pi 3 is a protective enclosure designed specifically for the very popular Raspberry Pi 3 Model B and previous RPi 2 / RPi B+ credit-card sized computers. Students, engineers and designers alike, all love the Raspberry Pi for its small size and big list of features and capabilities. While low cost and strong community support top the feature list, an area that challenges many Pi enthusiasts however is experienced first hand while breaking out connections to external hardware and peripherals. Attaching a few cables to the board immediately reveals how lightweight the device is and how vulnerable it is to physical harm. The Raspberry Pi, like most other development boards, is a small fully exposed circuit board with limited non-standard mounting features. Proto Armour for Raspberry Pi offers wrap-around protection and supplements the board's limited non-standard mounting capabilities with a host of structural support and standardized mounting features.

Made for Raspberry Pi 3 Model B

With several thousand Proto Armour for Raspberry Pi enclosures in the field, we've taken our proven design and made the necessary changes to be compatibile with the latest Raspberry Pi 3 Model B and previous RPi 2 / RPi B+ boards. Not only is this version compatible with the latest Raspberry Pi 3 Model B, it is also backwards compatible with the original Proto Armour for Raspberry Pi accessories and mounting  dimensions.

Durable Construction

Experimentation is often performed outside the safety of a lab environment. Gadgets usually contain breadboards and sensitive electronics that require a layer of protection, or better yet - a layer of armour. Proto Armour for Raspberry Pi 3 is made from aircraft-grade aluminum using state-of-the-art CNC equipment at our facility in Orchard Park, New York USA. Parts are machined to exacting specifications, resulting in an enclosure that fits your Pi like a glove. Many surface treatments are available, ranging from a cost-effective bare metal finish, to a professional looking anodized coating in a variety of colors.

Structural Modular Design

Gadgets sometimes require external components or subsystems that are mounted close by. Proto Armour for Raspberry Pi 3 features an assortment of threaded holes and structural reinforcements that facilitate the mounting of external components and subsystems directly to the case. Other versions of Proto Armour protective enclosure hardware is compatible with a variety of platforms such as Arduino development boards, Freescale Freedom Platform, and 'mbed' modules from ARM. In most cases, Proto Armour hole spacing allows for interlocking several enclosures into a single assembly. Accessories such as brackets and spacers are designed to be compatible across the product line where possible.

Micro SD Card Access

The Raspberry Pi features a Micro SD memory card that stores the operating system along with your programs and data.  Proto Armour for Raspberry Pi 3 includes a precisley machined port that permits external access to the memory card without needing to disassemble the case.

LED View Ports

The Raspberry Pi includes LEDs that indicate various status information. Proto Armour for Raspberry Pi 3 and Camera features a view port perfectly aligned with the two board-mounted LEDs. LED illumination reflects to outside the enclosure for easy viewing.  A second LED port is included for backwards compatibility with RPi 2 / RPi B+ boards.

Security Friendly

The Raspberry Pi is a very cool gadget. Whether it is a classroom setting where several Pi boards need to be attached to student benches, or at a hackerspace meetup where a new creation is on display, it is critical to properly secure sensitive and valuable hardware. Proto Armour for Raspberry Pi is assembled using machine screws that are threaded from the bottom and hidden from unintended guests. The included through holes facilitate mounting the enclosure directly to a tabletop using special tamper resistant screws. Cover plates are also available to prevent cable detachment and memory card removal.


While functionality and quality are equally priority number one, affordability goes without being said. In line with the Raspberry Pi's cost effective design, Proto Armour for Raspberry Pi 3 is designed for manufacture, resulting in a lower cost of manufacture that enables low cost of ownership. New enclosure and accessory design is a careful balance of functionality, robust construction, and affordability for all.

Anodized Finishes

Proto Armour for Raspberry Pi comes standard in a plain tumbled aluminum finish.  A variety of anodized color options are available at additional cost. All anodized finishes except for black have a minimum purchase quantity of 30 units.

  1. Best value RPi3 case 5 Star Review

    Posted by on 11th Apr 2018

    The Proto Armour case for RPi3 is extremely high quality and well worth the asking price, a far better choice for both securing the board and disipating heat than any cheap plastic enclosure, and much more robust and attractive than the thin folded steel or extruded case options. Made in USA to boot, whats not to like?

  2. Great as a standard case, not so great for frequent changes or OC 3 Star Review

    Posted by on 19th Oct 2015

    The case is solidly built and aligns well. Like others have said getting to the USB is difficult if you try to change/remove a wifi or BT nub, using usb extensions is mandatory. Changing the microSD is challenging as well. Very tedious to get Pi2 seated right w/o the o-rings falling off the mounts before you get the screws in. Optional heat sink plate was a waste of $13. Doesn't touch any of the components, only has a single foam pad that connects it to the CPU, and not even very closely. GPU and Power components go w/o any heat sink, in fact they will now be trapped with lower volume of air space. Not good design if you intend to use for RetroPie3 with overclock. Will be giving this to a co-worker and buying something else.

    Response from MobileApp Systems:
    We reached out to our customer to address these concern's and offered to inspect the products for any defects in workmanship. It's important that information stated as fact be accurate, and so we must clarify three points being made above.

    The thermal pad used in connection with the heat sink accessory does indeed come into contact with the CPU and aluminum heat sink. The pad material is not foam, but is an engineered material with a thermal conductivity specification appropriate for this use.

    The heat sink plate is designed to distribute heat over a greater surface area than that of the CPU itself. While it does not come in direct contact with the case housing, it does provide sufficient heat dissipation for the CPU under intense loads. Using this heat sink plate is optional, providing flexibility for those wanting to use an add-on board.

    Since the GPU is contained within the same SoC alongside the CPU, the GPU will benefit from the single thermal interface to the heat sink plate. The power supply design in the latest Raspberry Pi B+ and RPi 2 Model B boards changed to a high-efficiency switching regulator. Heat dissipation from these components are a small fraction of what was produced by designs found in earlier versions of boards (i.e. original RPi Model B). The heat sink plate is therefore dedicated to cooling the SoC (CPU/GPU).

  3. Best raspbespberry Pi b+/2 case 5 Star Review

    Excellent construction.

  4. the old and new PI case 5 Star Review

    Posted by on 26th Feb 2015

    We have about 100 of them in daily use and hope on more. We have select this case due to its construction. It so well made it still blows my mind. NEVER EVER would choose a different case.

    Well done and a good show case for a product made in the good old USA!

  5. best case ever 5 Star Review

    Very solid and well designed product!

  7. Beautiful work; needs a few changes 5 Star Review

    Posted by on 15th Dec 2014

    beautiful machining. ports are a little far set into the case making for some fiddling and light concern.

  8. Solid protection for my Pi 4 Star Review

    Posted by on 4th Dec 2014

    This is my third Proto Armour enclosure, so I obviously like them. Like my two Pi B enclosures, this B+ enclosure leaves me confident that my Pi is well protected. In this case, it was going into a household where it might get rough treatment, and I really wanted a Proto Armour enclosure for it.

    As with my earlier camera+B enclosures, there are a couple of issues that buyers should be aware of before purchasing. The SD/microSD card is very close to the rear enclosure flange: if you expect to change SD/micro SD cards routinely, that will be a problem. In particular, the microSD card can easily drop into the case if you don't get it seated correctly, and then you'll have to open the case to get it out (I know from experience!). Similarly, the extended flanges around the USB ports help protect the USB dongles, but it's hard to get the USB devices in and out, and the flanges may interfere with wireless signals.

    But if you're implementing a "production" Pi system that you'd like to set up once and know that it's well protected and solid, this is the case to buy!

  9. Good design 5 Star Review

    Posted by on 14th Nov 2014

    Great product! instructions are very clear and simple also like the fact they have included extra hardware in case you loose a screw.
    One item that could use some improvement is the open area for the USB port. When stacking USB devices next to each other the opening is very tight. This can be fix by using external USB cable. Perhaps this could be improved upon for future products

  10. Solid and secure design 5 Star Review

    Posted by on 10th Nov 2014

    Case is well built and designed. microSD card and dongles will be secured. One issue you will need to consider is a potential need to use USB risers for small WiFi and Bluetooth dongles. Otherwise they will be recessed into the metal case and their performance will suffer (particularly Bluetooth).
