Raspberry Pi 3 vs Pi 2 power consumption and heat dissipation

When shutting down the HDMI and USB on the Pi3, the current drops to 160 milliAmps. In my tests, this was roughly 200 milliAmps on the Pi2. Thus, shutting down hardware (if you don't need it), can be ...

What are the cooling requirements for Raspberry Pi 3?

More information on this will be available as and when the units start arriving with purchasers and we get a clearer picture of overclocking capabilities and such. To the best of my knowledge the ...

Paper printable case for Raspberry Pi 2?

I was only able to find this on Google. It should work for the RPi 2. It's in a PDF form instead of a nice SVG, but it looks like it could fit what you need.

Will the Pi Zero version 1.3 require a new case

I am sure it will be fine. The newer zero obviously has the same footprint when viewed from above, judging by the placement of the screw holes in relation to the GPIO breakout. The camera connector ...

I2C device inside case + GPIO ribbon outside case

The rev. 2 model A and B both have a breakout for a second I2C bus, with the caveat that you can't use it and the camera header at the same time (this is software switchable while the pi is running). ...

What size screws does the Raspberry Pi board use?

I've just had a look at the Raspberry Pi A/B/A+/B+/2 PCB mounting holes and they all seem to be a little over 2.5mm diameter so a M2.5 machine screw/bolt would be the best fit. I usually use Nylon M2....

My pi 2 doesn't fit into my B+ case

Interesting, I have the exact same case and it works. You just need to gently force the Pi in, it is a pain to get it in, and a pain to get it out also.

Raspberrry Pi 3 Lego case

The Raspberry Pi is designed to be an embeddable device. So long as the environment around the RPi isn't exceptionally warm and humid, the RPi will be fine in an enclosed container. You will never get ...

Does the PoE hat fit in the Raspberry Pi case?

I use it with standard RPi cases above on the 3+, the lid will fit but it gets hot in the office so the fan runs all the time, so I run it with the lid off as it is our main DNS box and I want it ...

Is it possible my raspberry pi to melt its plastic case at 55° degrees?

No.* At 55°C, the raspberry pi cannot melt its case. ABS plastic begins to soften at around 100°C. Regarding the Pi being damaged, don't worry about it. Raspberry Pies throttle back their CPU speed ...

What size screws does the Raspberry Pi board use?

Just to add to the already correct answers, there's enough leeway to enlarge the PCB holes to M3 size so that you can use standard PC floppy drive screws, of which any PC enthusiast is likely to have ...

Decrease Width of RPi Zero

No. As you can see below, on the Zero v 1.3 the camera connector extends completely to one end and the SD card holder to within a mm of the other -- and slightly outside that line there's a resistor (...

How much electromagnetic or radio interference is caused by a typical unshielded Raspberry Pi?

"How much it is radiating in the RF spectrum?" is a question that's easy to ask, but not to answer - at least not specifically. And if you did have the specific answers, they will only have meaning if ...

Are there raspberry pis small enough to be a smart watch?

Yes, there are ;) - and 3D-printed parts are pretty light. The limiting factor is the battery. The Raspberry Pi (no matter which model) draws too much power to be usable as a smartwatch with a light ...

Accidentally shorted C97 on the Raspberry Pi with a washer

Should I keep the Raspberry Pi 3 model B case opened while it is turned on?

This depends on how you're planning to use your PI's. I have approx 50 PI (all PI 3) on my site. Only 8 of them are used without case (they are somehow built in box) and 2 of them are used in ...

Should I keep the Raspberry Pi 3 model B case opened while it is turned on?

Heatsink within a closed case does not do much. With my old B+, the temperature is lowered by maybe 4 degrees - from 53 to 49 degrees. For the Pi 3, with it's 70-80 °C idle temperature, I would use ...

Raspberry Pi case ventilation necessary?

I would lean toward providing some ventilation in a case for the RPi 3B+, especially if it will be used as a media server. Heat will not only reduce the life of electronic components such as your CPU/...
