详细信息

Speedier Processor

The new model is a high-performance general-purpose computer, incorporating an improved quad-core 64-bit ARM Cortex-A72 CPU to rival desktop computers. For the first time, the Pi 4 is available in a choice of memory sizes, so with up to 8GB of RAM (LPDDR4), you will see your Pi being able to carry out much more complicated tasks easily.

Improved Networking

With true Gigabit Ethernet and PoE capability (requires additional PoE HAT); 2.4GHz and 5GHz 802.11b/g/n/ac Wi-Fi and Bluetooth 5.0 with up to four times the range of the old specification. All together these make the Raspberry Pi 4 Model B board an ideal fit for your next SBC-based IoT project.

Upgraded USB Capacity and Power

Pi 4 has four USB ports, two USB 2.0 ports and two of which have been upgraded to USB 3.0. The board has a USB Type-C connector for power input, instead of the Micro USB connector the Raspberry Pi 3 had, so you can consolidate your cable collection. The headphone jack has made a return too!

Dual Video Output

Two micro-HDMI ports, replace the single full-size HDMI connector on previous versions, allowing the Pi 4 to support 2 4k monitors. The Pi’s hardware decoding has also been improved to allow it to decode 4K video at 60 frames per second using HEVC encoding.

Backwards Compatible

You don’t have to worry about the Pi 4 Model B not working with any of your existing pi projects, as the 40-Pin GPIO header and software is fully backwards-compatible.
