Our new Raspberry Pi 4 Case: the SecurePi Case

September 30, 2019

Our new Raspberry Pi 4 Case: the SecurePi Case

We are excited to announce our new SecurePi Case for Raspberry Pi 4!

Working with legendary designer Mike Doell, we designed this case from the ground-up to work with the Pi 4, and it has some rather unique features, such as the following:

Cooling vents with baffles on the top of the case
    Optional security covers for the USB / Ethernet ports and power/HDMI ports, with a knock-out for Ethernet
    Taller height to accommodate all sorts of Pi HAT's.  The case works especially well with the PoE HAT.
    Clip together or screw together design.  If you want the convenience of clipping your Pi into the case and clipping the case together, you can do that.  If you want the security of screwing everything down, we include the screws so you can do so!
      Unlike most two piece cases, our case top is tall.  This means that you can easily work on your Pi when the case top is off, as most of the protection is built into the top

        Here are a few pictures showing the design progression.  We started with a 3D printed model, then we received first-shot prototypes in white, and our final prototypes came in black.  Our production version will have a matte finish, but other than that looks quite similar to the black prototypes.

        2nd Shot Prototype in Black (production will be a matte finish)


        Of course, I wouldn't be a mechanical engineer if I didn't do a bit of testing on the case.  We wanted to verify the cooling performance of the case in several scenarios: a 1-hour idle, and a 5 minute stress test.

        Here you can see that at idle, the Pi 4 is cooler by 5°C (9°F) at idle.  This is with only passive cooling.

        Here we are running a stress test of the Pi 4 with a PoE HAT attached.  Note, we have seen similar performance with the Pimoroni Fan SHIM.  As you can see, the Pi 4 runs a whopping 12°C (22°F) cooler in our case versus the official Pi case.  Also, as the test runs on, in the official case, the Pi hits its thermal limit and the processor begins to slow down. 

        We hope you like our new case!  It has been a fun project and we are so excited to finally share it with you.  We believe it is the perfect case for makers, educators, and even commercial/industrial applications.
