Raspberry Pi 4 出來了,和之前的版本最大的改變是多了 2GB/4GB 的記憶體版本可供選擇!熱烈預購中!!

《特色》
1. 使用 Broadcom 2711 四核心晶片(原本為 BCM2837B0)Quad-core Cortex-A72 64-bit SoC,單核心時脈可達 1.5GHz,有三倍速快。
2. 三種記憶體(LPDDR4 SDRAM)大小可選擇,分別是 1GB, 2GB, 和 4GB。
3. 乙太網路(Ethernet)達 True Gigabit Ethernet。
4. 支援藍牙5.0(Bluetooth 5.0)。
5. 兩個 USB 3.0 和 兩個 USB 2.0。
6. 支援雙銀幕輸出,解析度可達 4K。
7. 使用 VideoCore VI,可支援 OpenGL ES 3.x。
8. 可硬體解 4Kp60 HEVC 影片。

《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 VL805BCM54213PE 控制,因此可使用全速的 USB3.0 和 Gigabit 頻寬。
