UAV Flight Controller Saves Weight

When building autonomous airborne vehicles like drones or UAVs, saving a little bit of weight goes a long way, literally. Every gram saved means less energy needed to keep the aircraft aloft and ul…

Future Brings CPU Modules, And The Future Is Now

Modularity is a fun topic for us. There’s something satisfying about seeing a complex system split into parts and these parts made replaceable. We often want some parts of our devices swapped…

Hackaday Prize 2022: A CM4 Upgrade For Your Old IPad

There’s no shortage of nicely built tablets out there, but unfortunately many of them are powered by what are by now severely outdated motherboards. Since manufacturers releasing replacement …

Design Your CM4 Carrier With WiFi Performance In Mind

The Raspberry Pi Compute Module 4 has a built-in WiFi antenna, but that doesn’t mean it will work well for you – the physical properties of the carrier board impact your signal quality,…

Meet The RouterPi, A Compute Module 4 Based GbE Router

[Zak Kemble] likes to build things, and for several years has been pining over various Raspberry Pi products with an eye on putting them into service as a router. Sadly, none of them so far provide…

Did You Know That The Raspberry Pi 4 Has More SPI, I2C, UART Ports?

We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years, which is why it might have flown a little bit under the radar: the Raspb…

This Raspberry Pi Mini ITX Board Has Tons Of IO

The Raspberry Pi now comes in a wide variety of versions. There are tiny little Zeros, and of course the mainstream-sized boards. Then, there’s the latest greatest Compute Module 4, ready to …

The Raspberry Pi CM4 Begets A Form Factor

It has become the norm for single-board computers to emerge bearing more than a passing resemblance to the Raspberry Pi, as the board from Cambridge sets the hardware standard for its many competit…

The Compute Module Comes Of Age: Say Hello To The Real Cutting Edge Of Raspberry Pi

If we wanted to point to an epoch-making moment for our community, we’d take you back to February 29th, 2012. It was that day on which a small outfit in Cambridge put on the market the first …

Raspberry Pi With Some Serious Graphical Muscle

[Jeff Geerling] routinely tinkers around with Raspberry Pi compute module, which unlike the regular RPi 4, includes a PCI-e lane. With some luck, he was able to obtain an AMD Radeon RX 6700 XT GPU …

How Do You Make A Raspberry Pi On A Stick?

We agree with [magic-blue-smoke] that one of the only things more fun than a standard Raspberry Pi 4 is the Compute Module form factor. If they are not destined to be embedded in a system, these ne…
