Product Description

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

Proto Armour for Raspberry Pi 4 is a protective enclosure designed specifically for the newest Raspberry Pi 4 Model 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 4 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 4 Model B boards. Not only is this version compatible with the latest Raspberry Pi 4 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 4 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 4 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 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 4 includes a precisely machined port that permits external access to the memory card without needing to disassemble the case.

LED View Port

The Raspberry Pi includes LEDs that indicate various status information. Proto Armour for Raspberry Pi 4 features a view port perfectly aligned with the board-mounted LEDs. LED illumination reflects to outside the enclosure for easy viewing.

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 4 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.
