Gert releases VGA add-on for Raspberry Pi Model B+

September 11th, 2014

In case you have not seen it, there is a new B+ add-on design by Gert, the designer of the Gertboard, GertDuino and many other excellent boards.

Here is my work-in-progress hand wired prototype:

Banana Pi WiFi Tests – 8 adapters tested

September 9th, 2014

After updating my Raspberry Pi WiFi Tests to eight adapters, with and without a powered hub, I decided to test a Banana Pi with the same eight adapters – once again with and without a powered hub.

The three adapters above were tested in addition to the five tested in my Banana Pi Review, and I then tested all eight adapters with a powered hub as well.

I was pleasantly surprised at how well the BPi worked with power hungry WiFi sticks!

Raspberry Pi WiFi Tests – three more adapters

September 7th, 2014

I’ve added three more adapters to my Raspberry Pi USB WiFi adapter tests (now with eight adapters) for the Model A, Model B and Model B+

Of the eight adapters tested, three will work without needing a hub!

I also added test results showing all eight adapters with a powered USB hub.

You can find the tabulated test results, along with the Linux kernel output for each adapter at:

BPi-R1 Open-Source router

August 27th, 2014

I was browsing www.banana-pi.com and ran across a new product page – so fresh, that they did not even have a price listed!

Basically, they made a larger printed circuit board based on a Banana Pi, and added:

  • small gigabit switch (BCM53125)
  • 802.11b/g/n WiFi

Now this will make a really interesting router for OpenWRT… dual core A20 and 1GB of ram makes for a very powerful router!

It looks like they preserved most of the connectors from the Banana Pi (except for one USB host port) and added a laptop-style SATA connector on top.

Note the RTL8192CU WiFi module (now we know where the second USB port went) and the two antenna connectors.

For more specifications on the BPi this router is based on, see my BPi review :)

An expandable, dual core router with 1GB… who would have thunk it?

I’ll have to buy a couple for my lab so I can try them out, they may replace my Linksys WRT54G routers…
