https://youtu.be/TnCH3Bg95Ik This is a vintage VFD tube clock that uses Ethernet for both power and data. The power is provided using 802.3at PoE+ and a Molex PD Jack that contains both integrated magnetics and a PoE Type 2 PD controller. The IP stack runs on a Microchip PIC18F67J60 microcontroller that has an integrated Ethernet…
Radxa recently unveiled many news about its products, adding NVMe support to the Rock Pi 4 v1.4 model and launching a tiny Rock Pi S board for voice applications, and a Rock Pi PoE HAT for adding Power-over-Ethernet to the Rock Pi 4. Rock Pi S: presumably, this will be an open-spec community backed board…
The $20, 802.3af-compliant Raspberry Pi PoE HAT allows delivery of up to 15W over the Raspberry Pi 3 B+’s USB-based GbE port without reducing the port’s up to 300Mbps bandwidth. Power over Ethernet is a widely adopted standard that places power on the Ethernet cable along with the data. It has no effect on the…
Guys at Pi Supply released a very useful raspberry shield, to allow the POE supply to the beloved mini-pc. The backing campaign already gathered 2x the request, and 19 days are still running before it’s over, so hurry up if you are interested! The details: You can now power your Raspberry Pi and provide…
This cool project to integrate Arduino compatible technology with Power over Ethernet is pretty interesting. Isn’t RS-485 old technology? If by old, you mean “has 3 decades of bullet-proof reliability”, then yes. Despite being invented over 30 years ago, RS-485 has been proven very reliable and is still used globally in industrial automation today. Keep in mind…
