Best answer: Yes you can use two displays with a Raspberry Pi, but you will need to buy some other components depending on how you want to use those displays. You'll need an adapter with a DisplayLink chip or a VGA666 Adapter to use it as a true secondary monitor. You should also know in advance: this isn't easy to set up. An extended desktop solution The most common reason people want to use two monitors with a Raspberry Pi is to have an extended desktop environment like you would find on a larger, more expensive computer. This is doable with an inexpensive USB to VGA Displaylink adapter and a bit of knowledge about reconfiguring the kernel and X Windows configuration of your operating system. You'll need to make sure of two things on the hardware side: that the adapter you have is using a DisplayLink chipset and that the monitor you are using will accept a VGA signal, either through its own VGA port or through the use of an adapter. On the software side, you'll need to download the … [Read more...] about Can you use multiple monitors with the Raspberry Pi 3 B+?

The Raspberry Pi has been very popular among hobbyists and educators ever since its launch in 2011. It’s a credit-card-sized single-board computer with a Broadcom BCM 2835 SoC, 256MB to 512MB of RAM, USB ports, GPIO pins, Ethernet, HDMI out, camera header and an SD card slot. The most attractive aspects of the Raspberry Pi are its low cost of $35 and large user community following. Raspberry Pi: the Perfect Home Server by Brian Trapp: If you've got several different computers in need of a consistent and automated backup strategy, the RPi can do that. If you have music and video you'd like to be able to access from almost any screen in the house, the RPi can make that happen too. Maybe you have a printer or two you'd like to share with everyone easily? The Raspberry Pi can fill all those needs with a minimal investment in hardware and time.

A new version of the Raspberry PI 3 model B+ has released, and it is incredible update over the older model. Just over two years ago, I got Raspberry Pi 3 Model B. It was my first 64-bit ARM board. It came with 64-bit CPU. Here are the complete specs for updated 64-bit credit card size computer. From the blog post: Dual-band wireless LAN and Bluetooth are provided by the Cypress CYW43455 “combo” chip, connected to a Proant PCB antenna similar to the one used on Raspberry Pi Zero W. Compared to its predecessor, Raspberry Pi 3B+ delivers somewhat better performance in the 2.4GHz band, and far better performance in the 5GHz band Previous Raspberry Pi devices have used the LAN951x family of chips, which combine a USB hub and 10/100 Ethernet controller. For Raspberry Pi 3B+, Microchip have supported us with an upgraded version, LAN7515, which supports Gigabit Ethernet. While the USB 2.0 connection to the application processor limits the available bandwidth, we still see roughly … [Read more...] about Raspberry PI 3 model B+ Released: Complete specs and pricing
The Raspberry Pi Foundation has announced a new version of its modular compute platform: the Raspberry Pi 3 Model B+. The B+ has the same form factor and dimensions as the Pi 2 B and Pi 3 B, making it a drop-in replacement but with a better processor and connectivity. Compared to the Pi 3 B, the B+ adds many hundreds of MHz—it runs its quad core 64-bit Cortex-A53 processor at 1.4GHz, up from 1.2GHz—along with dual band 2.4/5GHz 802.11b/g/n/ac Wi-Fi and Bluetooth 4.2, up from 2.4GHz and Bluetooth 4.1. The Ethernet port has been upgraded from 100Mb/s to what is technically gigabit; it syncs at gigabit speeds, but the actual Ethernet controller is only USB 2, so transfer rates are limited to about 300Mb/s.Other connections are unchanged, four USB 2 ports, a 40-pin GPIO connector, an HDMI video output, camera and touchscreen ports, stereo/composite video, and a microSD slot for its software and operating system. It uses the same 5V/2.5A power as before and will also support … [Read more...] about Raspberry Pi 3 B+ has faster CPU, Wi-Fi, and easier compliance testing
