An ESP32 core board with wired Ethernet connectivity and PoE

The wESP32 is an ESP32 core board with wired Ethernet connectivity and Power over Ethernet that was designed to help Makers quickly create zero-setup single-wire-install connected devices. By combining a powerful microcontroller with excellent community support, 13 W of power, and reliable connectivity in a compact footprint, the wESP32 gives you a head start in your next IoT design and allows you to focus on your application.

  • Espressif Systems ESP32-WROOM-32 module with all the features, performance and community support that it brings to the table
  • Optional wESP32-Prog module for programming and/or serial console can be plugged in as needed or soldered in permanently
  • IEEE 802.3at Type 1 Class 0 compliant PoE with 12.95+ W of power available at the default 12 V output setting for V+
  • Optional 5 V output setting for V+ configurable by solder jumper with 5 W of power available
  • 3.3 V output with up to 6 W output power available (power taken from V+)
  • Applying external power to V+ is supported, in case PoE is not available
  • Applying power through the wESP32-Prog USB port is supported (only provides 5 V on V+)
  • High performance RJ-45 jack with optimized data path provides excellent data throughput allowing iperf UDP scores up to 90 Mbit/s
  • Compatible with PoE Mode A (power over data pairs) and PoE Mode B (power over spare pairs) and Auto-MDIX allowing the use of straight and cross-over Ethernet cables
  • Designed with full data and power path isolation to comply with the IEEE 802.3at 1500 Vrms isolation requirement
  • High quality PCB with 2 oz copper and mounting hole designed to sink heat away from the PoE PD controller for optimal thermal performance
  • 20-pin header footprint with 3.3 V, V+ power and 15 of the ESP32 GPIOs available for your application

The project is comming on CrowdSupply soon.

SinoVoip Unveils Open-spec Banana Pi BPI-P2 Zero SBC

SinoVoIP is going to launch their inexpensive Raspberry Pi Zero compatible, Allwinner H2+ powered board Banana Pi-P2 Zero. This is going to be the successor to Banana Pi M2 Zero. The new Banana Pi-P2 Zero combines support for PoE (Power-over-Ethernet) as well as a CSI camera interface.

The Banana Pi BPI-P2 Zero is almost identical to last year’s $21 Banana Pi BPI-M2 Zero with a few significant enhancements. The board attaches 8GB eMMC storage, as well as a 10/100 Ethernet port with Power-over-Ethernet support available via an optional PoE module. The new board doubles the weight to 30 grams and extends the smaller dimension by 22.5mm giving it a 65 x 52.5mm footprint.

Other features are almost the same as the M2 Zero, which itself is an emulation of a Raspberry Pi Zero W. The P2 Zero board can run Linux and Android on a 1.2GHz, quad -A7 Allwinner H2+, which is like an Allwinner H3, but with HD instead of 4K video support. The SoC integrates a Mali400 MP2 GPU.

The Banana Pi BPI-P2 Zero comes with 512MB DDR3, a microSD card slot, and a WiFi/Bluetooth module. Other features include MIPI-CSI, 40-pin RPi expansion, a mini-HDMI port, a USB 2.0 host port, and a power-only micro-USB OTG port.

Banana Pi BPI-P2 Zero specifications:

  • SoC: Allwinner H2+ quad-core Arm Cortex A7 processor with Mali-400MP GPU.
  • Memory:
    • 512MB DDR3 SDRAM.
    • 8GB eMMC flash
    • Micro SD card slot
  • Video Output: mini HDMI port
  • Connectivity:                    
    • 10/100M Ethernet with PoE support
    •  WiFi & Bluetooth via AP6212 module
  • The camera I/F: CSI camera interface
  • USB: 1x USB OTG port
  • Expansion:
    • 40-pin GPIO header with UART, SPI, I2C, etc…
    • 3-pin UART header for serial console access
  • Power Supply:                    
    • 5V/2A via micro USB port
    • Power-over-Ethernet (PoE)
  • Dimensions: 65 x 52.5mm
  • Supported OS: Linux, Android

No pricing or availability information was provided for the Banana Pi BPI-P2. More information may be found on SinoVoip’s Banana Pi BPI-P2 Zero wiki page.

AAEON’s VPC-5600S opens up new horizons for NVR technology

AAEON, an award-winning developer of network devices and embedded computers, launches the VPC-5600S, a network video recorder (NVR) with a possible eight PoE ports, each supported by their own LAN chips.

The VPC-5600S recently picked up coveted COMPUTEX d&i and Taiwan Excellence Awards, and AAEON network security division product manager Josh Chen has labelled it “the perfect surveillance system.” AAEON is currently the only company to offer NVRs featuring eight PoE ports with individual LAN chips. With this hardware specification and the device’s 7th Generation Intel® Core™ processor, users will receive the highest quality images from multiple sources without any danger of data loss. With an additional four USB3.0 ports and two LAN ports, the VPC-5600S can support up to 14 high-grade surveillance cameras. (more…)

White Paper: Cut the Cord with Power over Ethernet (PoE)

Providing AC power to each device individually is an extra cost especially for organizations when installing IP cameras, VoIP phones or network access switches and routers in the facilities. To help in this way some modern protocols, like USB and Ethernet, provide the power over the same data cable. However, USB is not designed for networking and long distance network applications. Besides that, the 900 mA at 5V in USB 3.0 is suitable for low-power devices like external hard disks but can’t provide enough power for high-power devices like switches and other network instruments. For these reasons, PoE (Power over Ethernet) can be the best choice.

PoE can provide power up to 30W beside data connectivity on any standard CAT-5/5e twisted-pair Ethernet cable, and supports 10Base-T, 100Base-T, 100Base-TX, and 1000Base-T Gigabit Ethernet interfaces.

The LEX Computech 3I390NX Series

As an example of an SCB (Single Computer Board) that provides PoE on its ports is a board called 3I390NX from LEX COMPUTECH which is based on the latest Intel Pentium Processor N4200/ N3350/E3950 Apollo Lake processor family. The Ethernet ports are provided by the Intel Ethernet controller i1211-AT.

3I390NX SCB features are:

  • Intel Apollo Lake N4200/N3350/E3950 CPU/chipset.
  • On Board 4GB DDR3L.
  • Display: HDMI, DP, VGA & eDP.
  • 5 x GbE (4 x PoE) LAN.
  • 2 x Mini PCIe.
  • 6 x USB.
  • HD Audio.
  • 2 x COM (1 x RS232 / 422 / 485 port (external), 1 x RS232 / 422 / 485 port (internal)).
  • Hardware digital Input & Output, 8 x DI / 8 x DO.
