Raspberry Pi Bumper for Raspberry Pi 5 review: Silicone protection for your silicon

Raspberry Pi has been releasing a slew of products in 2024. We’ve had the Raspberry Pi Pico 2, the Raspberry Pi 5 2GB, a new AI Camera, as well as two AI boards (the Raspberry Pi AI Kit and the Raspberry Pi AI HAT+). That’s in addition to new Raspberry Pi branded A2 micro SD cards and SSDs. But a $3

for the Raspberry Pi 5 was something of a curveball.

This one-piece flexible silicone rubber bumper is exactly that. Not a case, more of a means to keep your Pi 5 stuck to the desk, and not shorting out on that errant ****** you left sitting out.

But does it work? Does it interfere with the Raspberry Pi 5’s cooling? Is it any good? Let’s find out in what could possibly be my shortest ever review.

With the power off and the micro SD card, gently place the bumper on the underside of the Raspberry Pi 5. I found that working from the micro SD and “snapping” the corners into place was the easiest way. Once on, all of the ports are accessible and the micro SD card slot has its own cut-out for easier access. The power button is also easier to use, which sounds *******, but the rubber coating does make it softer to press.

If you are using any NVMe storage boards, like Pineboard’s HatDrive! Bottom or Pimoroni’s NVMe Base and NVMe Base Duo, then you are not going to be able to use the Bumper. If you are using an NVMe drive that attaches to the top of the Pi 5, like the official Raspberry Pi M.2 HAT+, Pineboard’s HatDrive! Nano or HatDrive! Top then you are good to go

With the bumper in place, my Raspberry Pi 5 was no longer skidding round my desk like a scene from The Fast and the Furious. It stayed in place on my cutting mat, and on my Ikea desk it didn’t budge when I poked it. It will move if enough force is applied, but the silicone rubber keeps it in place while also providing protection to the underside of the board. We’ve all accidentally shorted a component by resting it on something conductive, and this bumper lessens the chance of this happening to the Pi 5. There are 12 cut-outs on the underside of the bumper, used to draw cool air into the underside of the Raspberry Pi 5. The underside of the Pi 5 is also raised slightly from the bumper to allow for air to move.

All of the ports are accessible, with cut-outs to accommodate your cables, and in the case of the micro SD card slot there is a special cut-out which sees the micro SD card now flush to the perimeter of the bumper case. If you do any GPIO work, use any of the best HATs then ***** not as this case does not impede your work.

Does the Raspberry Pi Bumper Impact Thermal Performance?

The short answer, no. But I did run a stress benchmark to show that there is little difference. The test was completed using my usual benchmark test which logs data to a CSV file for analysis in a spreadsheet. The Raspberry Pi 5 4GB was not overclocked, running at the stock 2.4 GHz (1.5 GHz at idle).

The results are not very exciting. If you were expecting a massive heat issue, then I’m sorry to report that the Raspberry Pi Bumper does very little to impact thermals. With no case, just a bare Raspberry Pi 5 on my desk, with the Active Cooler on, the Raspberry Pi 5 idle temperature was 45 degrees Celsius. Under stress this jumped to 59.8 C, with the Active Cooler kicking in at 50 C to gently ***** the heat from the heatsink.

With the bumper on and the Active Cooler on, the idle temperature was 45°C, and stress hit 60.4 C! A 0.6 C difference between no bumper and bumper. Suffice to say, your Raspberry Pi 5 is perfectly fine in the bumper case.

Who is the Raspberry Pi Bumper for the Raspberry Pi 5 for?

I can see the bumper being useful in the classroom, the makerspace and your home workshop. It stops the Pi 5 sliding around, but keeps access to every single port and GPIO pin. This means we can hack around and not chase out Pi 5 across the desk when we plug in that heavy HDMI / Ethernet / power cable that pulls the Pi away from us.

The Raspberry Pi Bumper for the Raspberry Pi 5 is “just” a silicone rubber sleeve, and many of you will be thinking that you can 3D print your own, probably using one of the best budget 3D printers. But the cost of electricity, filament and wear and tear on your machine won’t leave you much change from $3. If Raspberry Pi ever releases a Bumper STL, we will be printing it in TPU, just for fun.

It’s $3, so it’s not a huge expense to grab a Raspberry Pu bumper for when you’re hacking on your Pi 5. If you want a case, then this isn’t for you. It won’t protect the GPIO pins, nor make the Raspberry Pi 5 look more like an appliance for your lounge / office. It’s not a groundbreaking innovation, but it is a genuinely useful product that provides some protection, without getting in the way.
