Knock off board

Mon Dec 03, 2012 10:28 am

I found a listing for a knock off of the Gertboard. It looks ok but is it breaking any trademark or copyright? It's full of surface mounted chips. And is listed as RASPBERRY Pi Multifunction I/O Extension Board (alternative Gert Board ) ARDUINO. At $50 shipped I think it's a bit overpriced for a knock off and it's about half the size of a real Gertboard as well.

I hesitated putting up a link in case of issues. but http://www.ebay.com/itm/330838954789?ss ... 1423.l2649 my first thought is they are not doing anything wrong. But I don't know for sure.

As they are clearly describing as an alternative to a Gertboard and not using the trademark getboard then it is quite legal. It is clearly very different from the Gertboard as well so nobody can accuse them of making a direct copy, not that there is any law that would prevent that.

Yup, that seems fine. Anyone can make add on boards as long as they don't infringe copyright or trademarks. That looks like a fairly well made device as well.

Ok cool. So now my next question. Isn't this a glorified UNO other than a PIC chip it seems very similar. Keep in mind I am not an electronics person I am still learning and the 2 UNO's I have are all wrapped up for Christmas presents. Don't tell my kids that though. To me the downside of this is really the price I got 2 UNO's with shields and 20x4 screens for less than this board. And a RTC module is only a few dollars. I guess in my head I am not wanting to have another toy but the more I look at it the more I want it. Dang the Gertboard I want one so bad even half a gert is looking good. :lol:

The only thing you could possibly accuse them of is being cheeky by using Gert Board alternative in their listing title. James won't have missed the complete lack of bibbly bobbly lights though. :lol:

You can never EVER have too many bibbly bobbly lights. I think they should be a legal requirement for all modern electronic equipment.

On the other hand, the people Xmas decorating the Empress Pub in Cambridge have gone a bit mad with the bibbly bobblies.

So just for James then.

- No leds
- only 5-bit Digital to Analog converter (DAC) with 0..5V output (GB has 8 or 10 bit)
- only four relay connections (GB has 6)


+ Realtime clock
+ barrel connector for power jack
+ Four PWM outputs (GB has 1 on port 18)
+ IR Remote Control input
+ Arduino Shield connectors
+ Power supply (Not needed with GB)

The ATMEGA328P uses 5V signal level, whereas on the GertBoard it's running at 3V3.

I don't know whether this board has buffers on the GPIO connections (GertBoard does).

It looks more "Arduinoey" than the Gertboard. That may be a good thing for some and a bad thing for others.
The board is designed as versatile, general-purpose data acquisition and control module and provides a direct connection to Raspberry Pi GPIO connector (26 pins).
Whereas the Gertboard is designed to teach people about computer interfacing.

Putting "RASPBERRY PI" first can be argued to give the impression it's a product of/from the foundation so probably is infringing trademark use, and I believe Gertboard is trademarked as well.

"Multifunction I/O Extension Board for the Raspberry Pi ( an alternative to Gertboard )" would be a safer, non-infringing, wording

Look at page 5 of the piplus manual.
You will see that the io is buffered wit 3v3>5v buffers.

PiPlus board includes the 3V- 5V buffers for I2C, SPI and Serial interfaces


Yep you are correct :-)
