The Raspberry Pi Foundation has launched an improved version of the credit card sized computer, the Pi 3. This 3rd serving of Raspberry Pi comes with Wi-Fi and Bluetooth baked in.
Raspberry Pi 3 is powered by a 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU, replacing the 900MHz 32-bit quad-core ARM Cortex-A7 CPU that's in previous generations. It comes with 1GB of RAM, integrated 802.11n wireless LAN and Bluetooth 4.1. The new devices are fully compatible with the previous generation Pis.
Broadcom has created a new SoC (system on chip) BCM2837 for Raspberry Pi 3 that retains the basic architecture of its predecessors BCM2835 and BCM2836. Due to this compatibility, projects running on previous generation chips will continue to work on the new one. You can also throw Pi 3 to the mix to expand your Pi cluster. I talked to Jason Plum of Arch Linux ARM and he told me that images for Raspberry Pi 2 will work fine on Pi 3 so nothing extra is needed. All those tutorials written for the previous generations will also work on the latest, obviously with the addition of Bluetooth and wireless.
The board design remains the same as well: the connectors are in the same place and have the same functionality. And, like previous generations, users can power the board with a 5V micro-USB power adapter. However, the Foundation is now recommending using a 2.5A adapter if you plan to connect power-hungry USB devices to the Pi 3.
This release celebrates the fourth anniversary of the Raspberry Pi Foundation. The device is available immediately through partners.
