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.

The RN2483 LoRa® Mote is a LoRaWAN™ Class A end-device based on the RN2483 LoRa modem. As a standalone battery-powered node, the Mote provides a convenient platform to quickly demonstrate the long-range capabilities of the modem, as well as to verify inter-operability when connecting to LoRaWAN v1.0 compliant gateways and infrastructure.
The Mote includes light and temperature sensors to generate data, which are transmitted either on a fixed schedule or initiated by a button-press. An LCD display provides feedback on connection status, sensor values and downlink data or acknowledgements. A standard USB interface is provided for connection to a host computer, providing a bridge to the UART interface of the RN2483 modem. As with all Microchip RN family of products, this enables rapid setup and control of the on-board LoRaWAN protocol stack using the high level ASCII command set.

很多人拿到 Pi 3B+ 之後會迫不及待的把原本在 Pi 3B 上所使用的 SD 卡拿到 Pi 3B+ 使用，但是會發現無法開機。這是因為 Pi 3B+ 使用新的晶片(BCM2837B0)，因此如果沒有安裝 2018-03-13 以後所發布的核心(kernel)或是韌體(firmware)是無法直接使用的。
2018-03-13:
* Raspberry Pi 3 B+ support
* WiFi is disabled until wireless regulatory domain is set (Pi 3 B+ only)
- The domain can be done through 'Raspberry Pi Configuration' (rc_gui),
'raspi-config' or by setting 'country=' to an appropriate ISO 3166
alpha2 country code in /etc/wpa_supplicant/wpa_supplicant.conf.
