3 Ways to Power Devices with PoE: Wall Plug, Multi-port Injectors, and Injector/Splitter Cables

4-port poe injector

I regularly browse new arrivals feeds of popular websites to look out for interesting products, and I’ve noticed Banggood has several inexpensive PoE plugs and injectors going for around $6, which is quite cheaper than I would have expected. Apart from MatchX LoRaWAN gateway, I’ve never really used PoE to power devices, but I may soon have another look on Raspberry Pi 4 board with a third-party PoE HAT. PoE is mostly interesting if you need to run long cables to your boards or IP cameras since using a single Ethernet cable for data and power saves on cabling. 24V/48V PoE Plugs for the European market Banggood had three PoE plugs with prongs made for the European market: 48V/0.5A (24W) PoE Wall Plug 12V/1A (12W) PoE Wall Plug 24V/1A (24W) POE Wall Plug All three plugs are visually identical with a LAN port to connect to your router, and a PoE port adding power to the data signal, and only …

Banana BPI-P2 Maker SBC with PoE Support Sells for $13 and Up (Promo)

Banana Pi BPI-P2 Maker PoE Module

Last year SinoVoIP introduced Banana BPI-P2 Zero board powered by Allwinner H2+ processor with 512MB, 10/100M Ethernet with Power-over-Ethernet, WiFi & Bluetooth, a mini HDMI port, and an 8 GB eMMC flash. They also launched a lower cost version without eMMC flash nor wireless module for $16, and the optional PoE module going for $6 extra. The company is now selling the board at a promotional price of $13 without PoE, and $19 with RT9600 POE module. The shipping fee is not included in those prices however, and in my case, the prices end up at respectively about $25 and $31 with shipping. Banana Pi BPI-P2 Maker specifications: SoC – Allwinner H2+ quad-core Arm Cortex A7 processor with Mali-400MP GPU. System Memory – 512MB DDR3 SDRAM.

Raspberry Pi PoE HAT Launches, But Refunds Offered due to Power Issues

Raspberry Pi 3+ with PoE HAT

The Raspberry Pi foundation has launched a good number of boards and  accessories, and although some people will question some of the design choices, their boards were fairly bug-free hardware-wise at launch, except for minor issues like the board rebooting while taking a photo with a Xenon flash. Recently they also had performance issues with Gigabit Ethernet in the  Raspberry Pi 3 B+ board, but that looks like more of a software issue. The Raspberry Pi PoE HAT announced with Raspberry Pi 3B+, but launched at the end of August for $20,  however suffers from a more serious issue as it somehow limits USB current to 200mA instead of the usual 500mA, meaning that’s fine with USB keyboard and mouse, but as soon as you connect more power hungry peripherals like a USB hard drive, all hell breaks loose. Let’s check out the specifications first: 802.3af PoE Fully isolated switched-mode power supply 37–57V DC, Class 2 device 5V/2.5A DC output …

Banana Pi BPI-P2 Zero Board Combines PoE, Camera Interface, and Allwinner H2+ Processor

Banana Pi BPI-P2 Zero

Allwinner H2+ quad core Cortex A7 processor has enabled some of the cheapest Arm Linux boards on the market with products such as NanoPi Duo or Orange Pi Zero with the latter now selling for about $9 and up. SinoVoIP also had their own inexpensive – and Raspberry Pi Zero compatible – Allwinner H2+ board with Banana Pi M2 Zero, and the company has now been working on another model dubbed BPI-P2 Zero which includes support for PoE (Power-over-Ethernet) as well as a CSI camera interface. Banana Pi BPI-P2 Zero specifications: SoC – Allwinner H2+ quad core Arm Cortex A7 processor with Mali-400MP GPU. System Memory – 512MB DDR3 SDRAM.

Banana Pi BPI-R64 Router Board is Powered by Mediatek MT7622, Supports 802.11ac WiFi, Optional PoE Module

Banana Pi BPI-R64

SinoVoIP launched several Banana Pi router boards in the past starting with Allwinner A20 based Banana Pi BPI-R1 in 2014, and followed by Banana Pi BPI-R2 board powered by a Mediatek MT7623 processor last year. Such boards normally include multiple Gigabit Ethernet ports, as well as at least one SATA connector, and in some cases an mPCIe connector for WiFi or LTE cards. THe company also launched Banana Pi BPI-W2 board a few months ago, but that model is more geared towards multimedia router use cases. The company has now unveiled Banana Pi BPI-R64 router board based on Mediatek MT7622 dual core Arm Cortex-A53 processor, five Gigabit Ethernet port, on-board 802.11ac WiFi, one “laptop” SATA port, as well as an optional PoE (Power-over-Ethernet) add-on board.Banana PI RPI-R64 board specifications provided by the company – which has not always shown to be accurate -: SoC – MediaTek MT7622 dual-core Arm Cortex-A53 @ 1.35GHz with dedicated network accelerator, 4×4 802.11n and Bluetooth …

Olimex Unveils ESP32-POE Board with… PoE Support

ESP32 POE

One of the differences between ESP8266 and ESP32 is the latter adds an Ethernet MAC, and as a results we have seen a few ESP32 boards with an Ethernet jack offering 10/100M connectivity, including Olimex ESP32-GATEWAY, Olimex ESP32-EVB, or ESP32 Monster Board. ESP32 Ethernet enabled boards are definitely in the minority however, and what’s even more difficult to find is an ESP32 board with Power-over-Ethernet (PoE) support. The good news is that if you’re looking for such type of board, Olimex is working on one based on requirements from their customers. Olimex ESP32-POE board specifications: Wireless module – ESP32-WROOM-32 module with 802.11 b/g/n WiFi and Bluetooth LE External Storage – micro SD card socket Connectivity – 10/100M Ethernet with PoE power management based on Si3402 IEEE 802.3at Type 1-compliant chip Expansion UEXT connector for Olimex modules 2x GPIOs stripes spaced at 1″ on 0.1″ step Debugging/Programming – micro USB port + CH340 Power Supply 5V via micro USB port Via …
