Rpi announcement

[Andrew Larkin]

Haven’t seen any discussion on yesterday’s Pi Day announcement.

 

New Raspberry Pi 3 B+

• Quad core 1.4GHz CPU (up from 1.2GHz) with improved heat spreader
• Dual band Wifi built in with whole board certified (not just wifi module)
• Gigabit ethernet – although limited to around 330Mbit throughput because it is routed through a USB2 chip.
• Header for PoE support with a PoE add-on in the works
• Same price (US$35)

I've got two on the way :-)

I'm curious to see if it can run both WiFi bands simultaneously as different networks...

I like the idea of PoE - but it's going to need a ~$35 hat as well as the new Pi.

From pics I've seen so far - it looks like it'll be _much_ harder to hack external antenna connectors onto the WiFi on these...

I find myself a little excited by PoE. While it was always possible to do it yourself it was fiddly. Having it inboard will make for good form-factor.

Doesn't seem really "inboard" to me...

One downside for the new board, it's got gigabit ethernet, which means it's using all 8 conductors in the network cable - so the old trick of using cheapo PoE splitters/injectors that just hook power up to the 2 unused pairs of 10/100 ethernet ports isn't going to work any more...

Poe switches are a lot cheaper now, so not necessarily an issue.   Look at the ubiquity 8 port switches for example.

It should auto negotiate down though?

Ive got a 3 B+, Ill bring it today for anyone who wants to have a little poke around / see it, its very pretty visually :^) 

[Aaron Power]

Do you also have an older Model 3? If so, any chance you could have a look at the "Run" pin location, please? It looks to me as though they have moved the location of these pins - again!

I'm designing a board at the moment that includes a watch-dog on these pins, but the location of the pins on the board keeps moving.

Thanks,
Aaron Power.
