一直想要購入一台 Raspberry Pi 觀察一下 release 週期，距離上次 Raspberry Pi 2 Model B 在 February 2015 公布的時間，也該是這時候了。
果不其然 Raspberry Pi Model 3 B 終於在 2/29 公告上市了。

Raspberry Pi 3 on sale now at $35 - Raspberry Pi https://www.raspberrypi.org/blog/raspberry-pi-3-on-sale/
主要的差別是 cpu 的升級 1.2 Ghz quad-cord ARM Cortex-A53 CPU
Ram 維持在 1G
增加了 無線網路 802.11n wireless 與藍芽
In celebration of our fourth birthday, we thought it would be fun to release something new. Accordingly, Raspberry Pi 3 is now on sale for $35 (the same price as the existing Raspberry Pi 2), featuring:
- A 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU (~10x the performance of Raspberry Pi 1)
- Integrated 802.11n wireless LAN and Bluetooth 4.1
- Complete compatibility with Raspberry Pi 1 and 2
Raspberry Pi 3 Model B SBC
The Raspberry Pi 3 Model B looks identical to the Pi 2 B at first glance. It is the same size and has much of the same components on board. So what is the difference? The new Pi 3 brings more processing power and on-board connectivity, saving you time with the development of your applications. Perfect for your Internet of Things (IoT) designs.
Pi 3 compared to Pi 2
More processor speed. The CPU on the Pi 3 is one and a half times faster at 1.2 GHz. Your Pi board performs better.
On-board connectivity. The Pi 3 features 802.11 b/g/n Wireless LAN and Bluetooth Classic & Low Energy (BLE). You can get connected much quicker without the need for any external device.
2.5 A power supply. With more processor speed and on-board connectivity, you'll need more power. Power supplies for previous Pi boards will not be sufficient. You will need the Official Raspberry Pi Power Supply (9098126 — white) or (9098135 — black).
New components. The Pi 3 features a chip antenna where status LEDs were located previously. The status LEDs are still on the board, right next to the microSD card slot.
New to Raspberry Pi?
The Raspberry Pi is a single computer board — developed to encourage and aid the teaching of programming and computing. It is also a fantastic starting point for the development of the Internet of Things (IoT) projects. The low cost and 'plug and play' nature of Pi makes for a board that is accessible to all and has numerous connectivity options. Pi is the perfect experimental tool, whether you want to use it as a desktop computer, media centre, server or monitoring/security device within your home. No limits. Linux-based operating systems run on the Pi with plenty of access to free software and downloads. What is more, there is a great Pi community out there — look atDesignSpark, the design engineer community at RS.
