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…

RoboPiLib_v0.81a

August 1st, 2014

I added a version 0.81a of RoboPiLib compiled under the latest Raspbian to the RoboPi page after receiving a report of linking issues with the previously uploaded version (that I generated on an old version of Raspbian).

I am currently working on the next revision of RoboPiLib, and I have started working on a Python library for RoboPi as well. The Python RoboPi API will be as close as possible to the C and Spin versions.


Raspberry Pi B+ with RoboPi

July 29th, 2014

RoboPi works on the new Model B+

I received my Raspberry Pi Model B + boards just a short while ago, and after admiring the four USB ports, mounting holes and better power regulation, I wanted to find out how my boards would work with it.

I tested EZasPi and Pi Jumper quickly – they worked… but I had to wait to find time to test RoboPi. Today I had time, and I am glad to report that RoboPi works well on the Raspberry Pi Model B +

I used one M3 18mm+6mm standoff to support RoboPi – while there was no mounting hole for it, there was space for the spacer to sit. I also added a nylon screw in the other RoboPi mounting hole, which provided insulation between RoboPi and one of the two dual USB sockets.

Just to be safe, I added some paper on top of the second dual USB jack – which will be replaced with electrician’s tape.

As you can see, just like EZasPi, RoboPi is offset roughly 9mm due to the change in the header position.

This actually works out well for the LCD display cable connector.

I had no problems programming RoboPi, and running demo code, with my Model B+ … RoboPi is definitely quite usable with the B+!
