New Raspberry Pi B+ announced

in hardware on (#3QP)
story imageThe Raspberry Pi keeps getting better: an updated version of model B Raspberry Pi has been announced by the Foundation. Looks like a great device.

Main changes are:
  1. More GPIO. The GPIO header has grown to 40 pins, while retaining the same pinout for the first 26 pins as the Model B.
  2. More USB. We now have 4 USB 2.0 ports, compared to 2 on the Model B, and better hotplug and overcurrent behaviour.
  3. Micro SD. The old friction-fit SD card socket has been replaced with a much nicer push-push micro SD version.
  4. Lower power consumption. By replacing linear regulators with switching ones we’ve reduced power consumption by between 0.5W and 1W.
  5. Better audio. The audio circuit incorporates a dedicated low-noise power supply.
  6. Neater form factor. We’ve aligned the USB connectors with the board edge, moved composite video onto the 3.5mm jack, and added four squarely-placed mounting holes.
The price is still $35.

Interestingly, Hackaday was there first, via a post just yesterday about a guy who got one of these things even before they were announced: probably a simple shipping error. They point out that the new form factor means old cases won't work. And they - and I - are excited about the better SD slot too: that was an important defect.

Woo hoo! (Score: 1)

This is the right kind of progress. I just bought a RaspbPi to play with, and was immediately kind of put off by the sketchy SD card slot and having to swap out keyboard for USB keys because of the lack of USB ports. Furthermore because the USBs are unpowered you simply can't put an external hard drive on them, which kind of limits anyone hoping to make a NAS controller out of them or something.
