Posted on 2018 年 08 月 27 日 by service

※改版中，暫時缺貨！

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

A Raspberry Pi 3 Model B+
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+。

[產品] Raspberry Pi 3 Model B+(現貨)

Posted on 2018 年 03 月 21 日 by service

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。

Raspberry Pi 3B+ 出來了，與 Pi 3 最大的改變是網路效能增加了! 現貨供應中!!

《WiFi 網路性能比較》

	Tx bandwidth (Mb/s)	Rx bandwidth (Mb/s)
Raspberry Pi 3B:	35.7	35.6
Raspberry Pi 3B+ (2.4GHz):	46.7	46.3
Raspberry Pi 3B+ (5GHz):	102	102

資料來源：LibreELEC

《Ethernet 網路性能比較》

	Tx bandwidth (Mb/s)	Rx bandwidth (Mb/s)
Raspberry Pi 3B:	94.1	95.5
Raspberry Pi 3B+:	315	315

資料來源：LibreELEC

Pi 3B+ 這次新增了 MaxLinear MxL7704 電源管理 IC，可有更好的溫度管理策略。例如在 70°C 以下可以使用 1.4GHz 全速運轉；但超過了 70°C 就會降到 1.2GHz 的速度。可用 Sysbench 看溫度/頻率的曲線圖。

圖片來源：RASPBERRY PI 3 MODEL B+ ON SALE NOW AT $35

新增四根 PoE 的 Pin 腳支援，並有對應的擴充板(HAT)。

圖片來源：RASPBERRY PI 3 MODEL B+ ON SALE NOW AT $35

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，例如官方電源和品牌電源。

更多訊息可以看 Eben 的介紹。

《沒有改變的部份》
