![]() It's also attractive to scientists and the burgeoning artificial intelligence market, since it can be used in proof-of-concept prototypes like robots or image sensors. This rather unorthodox process means that the Raspberry Pi is best suited for tinkerers and makers, who might use it as the brains of a DIY weather station or even a TV embedded in a bathroom mirror. Instead, you have to install your own operating system (typically, the Linux-based Raspbian) onto a microSD card and slip that into a slot on the Pi 4's underside for it to work. Raspberry Pi boards don't have any type of hard drive, and they're not designed to run Microsoft's Windows 10 operating system. In addition to 4GB of RAM, you get a Broadcom quad-core processor running at 1.5GHz, four USB Type-A ports, two micro HDMI video outputs, a gigabit Ethernet jack, and radios for 802.11ac Wi-Fi and Bluetooth 5.0.ĭespite all of these familiar components, two major things are missing that set the Pi 4 apart from the legions of cheap tiny desktops you'll find on Newegg or Tiger Direct. This diminutive circuit board features all the building blocks of a consumer PC, scaled down. (Opens in a new window) Read Our Raspberry Pi 3 Model B Review It's hardly the only inexpensive single-board computer out there, but thanks in part to the efforts of its creator (the nonprofit, education-focused Raspberry Pi Foundation), it's the best known. It measures 2.2 by 3.4 inches and stands about 0.6 inch tall. The Raspberry Pi 4 is a tiny single-board computer, which means that all of its components, from the memory to the USB ports, fit on one PCB without add-on cards or accessories. Altogether, though, the improvements are significant and make the Pi 4 a compelling maker board, a hobbyist's best friend, or even a budget desktop PC for those willing to tinker. The improvements also bring a higher price-the $55 version we tested, with 4GB of onboard memory, costs a $20 premium over the $35 base price. With all this extra potential in a board much the same size as earlier Pi models, comes a lot of heat that could lead to shutdowns, especially if you're using the Pi 4 to stream video or perform other such resource-intensive tasks. ![]() It packs cutting-edge features like USB-C power input, two video outputs that can each run an external 4K monitor, and a choice of RAM complements-a first for any Raspberry Pi. The Raspberry Pi 4 is the most powerful Pi yet. ![]() When taxed without an active cooling source, struggles with overheating.How to Set Up Two-Factor Authentication.How to Record the Screen on Your Windows PC or Mac.How to Convert YouTube Videos to MP3 Files.How to Save Money on Your Cell Phone Bill.How to Free Up Space on Your iPhone or iPad.How to Block Robotexts and Spam Messages.
