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.
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.
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
As one of the smallest systems around there are so many amazing things you could do with the Raspberry Pi if it was self-powered and portable. Introducing PiJuice! A fully uninterruptible power supply that will always keep your Raspberry Pi powered.
Our revolutionary PiAnywhere technology contained in every PiJuice HAT – is the best way to take your Pi off the grid! The real time clock (RTC) on board will let your Pi know what time it is even with no power input or internet connection. Alongside this is an integrated microcontroller (MCU) chip which will manage soft shut down functionality and a true low power deep sleep state and intelligent startup.
You will be able to always keep track of the charge levels and other info with the two built-in tri-coloured RGB LEDs, trigger events and scripts with the three programmable buttons and since the PiJuice will use up to just five of your GPIO pins (just power and I2C), the rest are free to diversify your project. The stacking header allows you to continue to use your existing HATs and add-ons with PiJuice.

BP7X battery – original battery from Motorola Droid 2 (A955) – 1820mAh battery
Microcontroller is an ST Micro STM32F030CCT6 ARM Cortex-M0, 48MHz, F64KB, R8KB, I2C, SPI, USART, 2.4-3.6V
Charge IC – BQ24160RGET Charger IC Lithium-Ion/Polymer, 2.5A, 4.2-10V
Optional spring pin – Mil-Max 0929-7-15-20-77-14-11-0
Compatible with any 4 pin battery on board that can be used with 00-9155-004-742-006 battery contacts from AVX including the BP7X, BP6X, and any compatible batteries including the 1600mAh and 2300mAh
ones from CameronSino (CS-MOA853SL and CS-MOA855XL)
There is an on board 4 pin screw terminal block for larger off board batteries. Any single cell LiPo / LiIon is compatible. However, you use your own sourced battery at your own risk. We HIGHLY RECOMMEND using
a battery with an internal protection circuit and a NTC (temp sensor)
Optional header for offboard button – connected to same output as SW1
6 pin breakout header – with two GPIO from the ARM Cortex-M0, Vsys, 5v0, 3v3, GND connections
Header for optional off board solar panel / wind turbine etc.
Optional RF Shield attachment – Harwin S02-20150300 (can also double as an inexpensive heatsink)
Input voltage range – 4.2V 10V
Output voltage – 3.3V and 5V
Output amperage – maximum current at 5V gpio is 2.5A and at VSYS output 2.1A, but also this depends heavily on battery capacity. For BP7X have measured around 1.1A at 5V GPIO and around 1.6A at VSYS
output. Obviously, this also depends heavily on the current draw demanded by the Raspberry Pi/device itself. To achieve a maximum of 2.5A it will need battery over 3500mAh.

由於 UP Board 所使用的 CPU 為 Intel Atom x5-Z8350，在 Intel 網站的規格為 64 位元 4 核心，時脈可達 1.92 GHz。乍看之下是比 Raspberry Pi 3 的處理速度快上不少，但 ARM 和 X86 是不同架構，而且操作上的反應速度除了和時脈有關，不同的執行條件也會有差異。
UVC(USB Video Class)就是 USB device class 視訊裝置在不需要安裝任何的驅動程式下隨插即用，包括網路攝影機(Webcam)、數位攝影機(Digital Camcorders)、類比影像轉換器(Transcoders)、電視卡(TV Receiver Card)等。而在 Linux 上如果有一個支援 UVC 的 Webcam 插到 USB，就會向 Kernel 註冊為 Webcam 設備，裝置節點為 /dev/videoX。
V4L2(Video4Linux 2nd)是一套 Linux 針對視訊設備(例如 Webcam)所定義好的 Userspace API，因此硬體廠商只要能實做 API 的功能，就能讓使用者透過統一的介面控制硬體。如此一來上層的使用者就即使不知道硬體的廠牌與底層的實做方法，只要知道呼叫相同的函式就能得到相同的結果，如下圖。
