圖片來源:Which Pi Do I Have? Includes Pi 4

Raspberry Pi 一路從 Model 1B、Model 1A、Model 1A+B+2B3B3B+ 到最新的 Pi 4B,外觀長的大同小異。特別是 Pi 4 有四個版本,外觀上要怎麼分辨呢?

《結論,從 RAM 的印刷來看》

  • 1GB – SEC928 或是 4HBMGCJ(Samsung)
  • 2GB – D9WHZ(Micron) or SEC940
  • 4GB – D9WHV(Micron) 或是 4HMMGCJ(Samsung)
  • 8GB – D9ZCL(Micron)

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。

[產品] Raspberry Pi PoE HAT (Power over Ethernet) 擴充板

Raspberry-Pi-PoE-HAT-4in1

The Raspberry Pi PoE HAT powers a Raspberry Pi 3 Model B+ via an Ethernet cable. Power-sourcing equipment is required on the Ethernet network.

《特色》

The Raspberry Pi Power over Ethernet HAT is a small accessory for the Raspberry Pi computer. It can only be used with the Raspberry Pi 3 Model B+ (launched March 2018). The PoE HAT allows you to power your Raspberry Pi using Power over Ethernet–enabled networks; for this product to be used, the network it is connected to needs to have power-sourcing equipment installed.

Supplied with this product

  • Raspberry Pi PoE HAT
  • Mechanical spacers

Other hardware needed

  • Pi 3B+/Pi 4B
  • An Ethernet cable
  • Power-sourcing equipment for a 802.3af Power over Ethernet network

Connecting your PoE HAT to the Raspberry Pi

  • Before installing the PoE HAT, you must attach the supplied spacers in the four corners of the board
  • Then connect the Raspberry Pi PoE HAT to the two 0.1” headers (40 + 4) that are fitted on the Raspberry Pi
  • Once the PoE HAT board is connected, you can power the Raspberry Pi through its RJ45 network connector

Disconnecting your PoE HAT

  • Take care when separating the HAT from the Pi
  • Pull evenly so that it detaches from all the pins at the same rate; do not pull one end of the connector off before the other

Additional information

No modification to the main Raspberry Pi board is needed for this product to work. Please ensure that your Raspberry Pi’s software is up to date for all functionality to be available. The PoE HAT is fitted with a small fan that is controlled by the Raspberry Pi via I2C. The fan will turn on and off automatically depending on the temperature of the main processor on the Raspberry Pi.

《規格》

The Raspberry Pi PoE HAT is an add-on board for the Raspberry Pi 3 Model B+. It allows the Raspberry Pi to be powered via a power-enabled Ethernet network.

  • 802.3af PoE
  • Fully isolated switched-mode power supply
  • 37–57V DC, Class 2 device
  • 5V/2.5A DC output
  • 25mm x 25mm brushless fan for processor cooling
  • Fan control

《安全提醒》

  • Shall only be powered using 802.3af-compliant power sourcing equipment; any external power supply used with the Raspberry Pi shall comply with relevant regulations and standards applicable in the country of intended use
  • Should be operated in a well-ventilated environment, and should not be covered
  • Should be placed on a stable, flat, non-conductive surface while in use, and should not be contacted by conductive items

Instructions for safe use

To avoid malfunction or damage to your Raspberry Pi product, please observe the following advice:

  • Do not block or obstruct the fan
  • Do not insert anything into the fan at any time
  • Do not expose the product to water or moisture, and do not place it on a conductive surface whilst it is in operation
  • Do not expose it to heat from any source; the product is designed for reliable operation at normal room temperatures
  • Take care whilst handling to avoid mechanical or electrical damage to the printed circuit board and connectors
  • Avoid handling the Raspberry Pi while it is connected to a power outlet; only handle by the edges to minimize the risk of electrostatic discharge damage
  • All other peripherals used with the Raspberry Pi should comply with relevant standards for the country of use and be marked accordingly to ensure that safety and performance requirements are met; these peripherals include, but are not limited to, keyboards, monitors, and mice used in conjunction with the Raspberry Pi

* 注意:本商品不包含 Raspberry Pi 3 Model B+。
