In addition to the built in heat sink, small ventilation slots on the bottom help keep the Raspberry Pi cool. We included rubber feet to raise the enclosure so it just hovers underneath your television. It only takes seconds to drop your Raspberry Pi into it’s amazing new home and show it off on your counter top. Supplied with the case is a thermal pad and 4 screws for the simplest Raspberry Pi case assembly on the market. We wanted to ensure we didn’t sacrifice form over function, so we used the aluminum housing of the case to provide a built in heat sink. This is the first affordable Raspberry Pi case made out of aluminum. But once it's out of your hands, it blends in with your entertainment system. Our case is made of a beautiful aluminum core heat sink that is sandwiched between two black, soft touch shells that feel amazing in your hands. We will ensure our case is adjusted to fit the latest Raspberry Pi specifications. Not only does it give your Raspberry Pi a very stylish look but it also keeps your CPU temperature reliable down to a level where no throttling is necessary.Īnd the aluminum heatsink will not reduce the WiFi signal quality, quite the opposite, it even results in a stronger signal than you would see with no case.The perfect home for your new Raspberry Pi 4. If you use the Flirc case for your digital picture frame and glue it to the back of your display, then make sure to turn the Flirc case upside down.ĭo it this way, and you can easily take out the SD card or even the board because you have access the screws and don’t need to loosen the case from the display. Here is a tip that I learned from on of my readers. So the answer to if there is any reduction in WiFi quality when the Raspberry Pi 4 is put into the Flirc case, is clear: on the contrary! The signal is even stronger! Maybe one of my readers with a physics or engineering background can help me understand why this is! A final tip that can save you a lot of headaches I actually repeated the testing to make sure that I hadn’t mixed up the screenshots but the result was the same. This was something I didn’t expect at all. The first position was about 5m away from the WiFi access point.Īgain, the WiFi performance of the Flirc case showed a higher link quality (74%), compared to 66% of the “naked” Pi 4. I then took the Raspberry Pi completely out of the Flirc case and ran the same test again without any case. I started the program with wavemon Onboard WiFi performance test results
FLIRC PI 4 INSTALL
I took my Raspberry Pi 4 with 4GB and put it in a Flirc case and installed the network monitoring software wavemon with sudo apt install wavemon -y But doesn’t WiFi performance suffer in a metal box?īut there was one question that I couldn’t find answered anywhere? Wouldn’t the onboard WiFi performance suffer when the Raspberry Pi was put in a metal casing? And at around US$16, it is even quite affordable. While you may not need it so urgently to keep the Raspberry Pi cool, it still looks so much better than the standard plastic case. And there may be more of those in the future.Ī few variations of the Flirc case have come up by competitors but I find Flirc still the best value for money deal out there.īy the way, the Flirc case is also available for the Raspberry Pi 3 and even the Pi Zero. I would strongly recommend to anyone who is building a 4K digital picture frame to use the Flirc case to keep the Raspberry Pi 4 cool even during hot summers. But for a digital picture frame, the only acceptable solution is passive cooling. The dynamic Raspberry Pi community immediately came up with solutions like fans in all sizes and ludicrous monster heatsinks. Through a firmware update, the Raspberry Pi foundation was able to reduce it somewhat but the case still got quite hot especially in warmer surroundings. This meant that even in hot summers, the Pi 3’s temperature never exceeded 60☌ (140☏) degrees in the little plastic case.īut when I started experimenting with the Raspberry Pi 4 model and 4K displays, the temperature went up to 80☌ (176☏) degrees. As image viewers don’t require a lot of processing power, the CPU hardly went beyond 10% utilization. In the past, my digital picture frame projects used the Raspberry Pi 3.
But if you want something nicer looking, which at the same time reduces the temperature of your CPU by up to 20 degrees, then it’s time to look at the Flirc cases.īut I was wondering: Doesn’t the metal enclosure impact the onboard WiFi performance? I was in for a big surprise. The original plastic Raspberry Pi case is cheap and does its job.
