產品簡介

The ultimate Raspberry Pi! a faster quad-core CPU, support for dual displays at up to 4K resolution, Gigabit Ethernet, USB3.0, wireless LAN, Bluetooth 5.0, and USB-C power. That's desktop PC performance!

 The overall form factor remains the same, so you'll still be able to use HATs and pHATs as before, but due to the changes to the ports on the Raspberry Pi 4, we've designed a brand new Pibow Coupé 4 case in three fetching colour-ways.

產品特性

As always with new Raspberry Pi models, you'll need the latest version of NOOBS or Raspbian to run on your Raspberry Pi 4. We sell a pre-imaged 32GB NOOBS card separately, or you can get one with our fully-loaded Pimoroni Raspberry Pi 4 Complete Starter Kit.

《Desktop-level performance》

The faster 1.5GHz 64-bit quad-core CPU on the Raspberry Pi 4's Cortex A72 SoC, coupled with the up to 4GB LPDDR4 RAM give performance comparable to entry-level x86 desktop PCs. You'll see significantly faster boot speeds, and much better performance for CPU-heavy tasks like emulation and media centre usage; much snappier all round!

The Raspberry Pi 4 moves to USB-C power meaning that you'll need a new USB-C power supply that can supply 5V at 3A. We've got a couple of different options: a worldwide USB-C power supply, and the official Raspberry Pi power supply.

Significantly faster IO傳輸速度提高10倍

The Raspberry Pi 4 has two USB 3.0 ports, for up to 10x faster transfer speeds than USB 2.0, perfect for connecting fast peripherals like SSDs and flash drives. There are also two USB 2.0 ports for connecting less speed-dependent peripherals like keyboards and mice.

The ethernet jack on the Raspberry Pi 4 moves to true gigabit speed, for super-speedy wired networking and, as with the Raspberry Pi 3 B+, there's Power-over-Ethernet capability too (requires additional Raspberry Pi PoE HAT).

4K display support, dual micro-HDMI

There are dual micro-HDMI ports that support up to 4Kp60, to use your Raspberry Pi 4 with much larger displays with crisp, sharp, high resolution. Use the H.265 4Kp60 hardware decoding to watch 4K movies in your favourite media centre distro.

For the first time, you'll be able to use dual HDMI displays with the Raspberry Pi. This is great for working on a bunch of different tasks at the same time without having to work in tiny windows.

If you need a micro-HDMI adapter to use your existing HDMI cable with the Raspberry Pi 4 then we've got you covered!

Bluetooth 5.0 and wireless LAN2倍速度+4倍範圍

The shift to Bluetooth 5.0 (from 4.2 on the Raspberry Pi 3 B+) means you'll gettwice the speed (2 Mbit/s) and four times the range (50m outdoors, 10m indoors) that you did with the previous generation. You'll get better power efficiency compared with Bluetooth 4.2 also.

《電源接頭》
POWER_CU-500x333
電源接頭從 USB micro-B 改成使用 USB-C,使用 5V/3A 以上電源供應器才能穩定使用。

《視訊接頭》
HDMI_CU-500x333
視訊接頭從 type-A(full-size) HDMI 接頭改為兩個 type-D (micro) HDMI 接頭。

《乙太網路和 USB 接頭對調》
USB_ENET_CU-1-500x357
乙太網路可支援 Full-throughput Gigabit 速度,並和 USB 接頭位置對調,簡化佈線的困難度。由於 USB 和 Ethernet 分別使用 VL805 和 BCM54213PE 控制,因此可使用全速的 USB3.0 和 Gigabit 頻寬。
