[產品] Raspberry Pi 3 Model B+(現貨)

SONY DSC

與 Pi 3 最大的改變是網路效能增加了,CPU 時脈也從 1.2GHz 微增加到 1.4GHz。

《新的改變》
1. 使用 BCM2837B0 晶片(原本為 BCM2837) 64-bit quad-core ARM Cortex-A53,單核心時脈可達 1.4GHz。
2. 使用 Cypress CYW43455 雙頻晶片(原本為 CYW43438),支援 2.4GHz 和 5GHz 雙頻,並支援 Bluetooth 4.2。
3. 使用 LAN7515(原本為 LAN951x),支援 Gigabit Ethernet over USB 2.0。
4. 支援 Power-over-Ethernet,由四根新增的 Pin 做控制,但要搭配官方擴充板。
5. 更好的溫度管理,在不同溫度下可自動調整 CPU 速度。

由於 CPU 時脈更高,並且支援 5GHz 無線網路,因此 Pi 3B+ 的電源需求更高,建議使用高品質的 5V/2.5A,例如官方電源品牌電源

《沒有改變的部份》
1. 和 Model 3B 一樣的外型與尺寸。
2. PCB 板固定螺絲開孔處相同。
3. USB、Ethernet、A/V、HDMI、micro SD 和 microUSB 位置相同,尺寸也相同。
4. Camera、Display 和 40-pin GPIO 位置也相同。

The Raspberry Pi Compute Module 3 (CM3) and Compute Module 3 Lite (CM3L) are DDR2-SODIMM-mechanically-compatible System on Modules (SoMs) containing processor, memory, eMMC Flash (CM3 only) and supporting power circuitry. These modules allow a designer to leverage the Raspberry Pi hardware and software stack in their own custom systems and form factors. In addition the modules have extra IO interfaces over and above what is available on the Raspberry Pi model A/B boards, providing more options for the designer.

《特色》

The Compute Module 3 contains the following components contained within a 200 pin SODIMM design:

  • Broadcom BCM2837 processor
  • 1Gbyte LPDDR2 RAM
  • 4Gbytes eMMC Flash
  • 35u hard gold plated IO Pins
