Raspberry Pi's PoE HAT Ships For $20, Tosses in a Free Fan (linuxgizmos.com)
Raspberry Pi is offering a Power-over-Ethernet HAT board for the RPi 3 Model B+ for $20 that ships with a small fan. Per blog LinuxGizmo, the "802.3af-compliant 'Raspberry Pi PoE HAT' allows delivery of up to 15W over the RPi 3 B+'s USB-based GbE port without reducing the port's up to 300Mbps bandwidth." From the report: The Raspberry Pi PoE HAT features a fully isolated switched-mode power supply with 37-57V DC, Class 2 input and 5V/2.5A DC output. The HAT connects to both the 40-pin header and a new PoE-specific 4-pin header introduced with the B+ located near the USB ports. To enable PoE, you need power sourcing equipment, which is either "provided by your network switch or with power injectors on an Ethernet cable," writes the foundation in a blog post.
Linux at its best
Has nothing at all to do with Linux, but the hardware on the Pi. Ethernet connections go though USB 2.0, which limits the bandwidth.

The whole point of the Pi project was to make a learning tool for students as cheaply as possible. There are hundreds of other single board computers out there with more features and bandwidth. Use the right tool for the job.

They've also been *incredibly* popular in industry. It's pretty common to need a SBC to do some shit and it's not performance sensitive. The fact there are cheaper and more powerful ones doesn't really matter: the Pi is well understood, easy to source next day, and well documented and available for long periods of time. Saving a few bucks is nothing compared to the engineer time not spent messing around.
Likewise the Arduino has revoloutionised vendor devkits.
Weirdly these threads seem to be full of people basically complaining you don't get a fast desktop for 25 dollars.
