Hi Tombo,


It should go into production this month. Production takes a few weeks, but it should be shipping very very soon. We already hand-built the first samples and are testing them now.


Quite possibly :) Hello again Tombo!

Welcome to the Netduino Community,

Chris


I thought you were out in Utah. Did you have to move to NY for this new gig? I still use my Zwave modules and that has been pretty steady. Nice to see some more .Net automation type projects still alive. Hope this one grows.

Next up are Piezo Buzzer, Ethernet, and SD Card modules--coming soon. Several dozen modules will ship this year...and we welcome you to build your own as well

This makes me very very very happy!

Can you even hint at what some of these might be?


Sensors? (Ping? Light? Tilt? Sound? Temperature? Humidity? Flex? Infrared?)
Voice recognition?
RFID?
GPS?
Imaging?
Bluetooth? Wifi?
Some sort of Robotics platform?

Several dozen is a lot!


Are you still on par for releasing 'several dozen modules' this year?

As far as I'm aware, "Several dozen modules will ship this year" was refering to both Secret Labs and 3rd party module builders. I know that 1 Module builder has slowed their production plans, and at least 2 others have moved them forward. I think we'll see at least a dozen total modules by the end of the year, +/- 4

Im not sure if you are being serious or not, given that there are already 8 modules, which is already "12 +/- 4" currently available (not including the shieldbase)...

nitpicking, Go! is still new, when the protocol is fully documented and finished, and shielbase is fully implemented, this is not an problem anymore.. I guess this is how bleeding edge is, I'm atleast looking forward to all the goodies that are coming, even if it's not "multiple dozens", I'm more than happy when we get stuff that makes it easier to create own modules, than to buy small simple modules for one button each and so on.

I was being serius I hadn't bothered to actually count how many were already on the market.

We currently have 9 modules (12 if you count the SD Card Module, power supply from Nwazet and the breakout from Matt)
Chris has said that the Ethernet is currently going under acceptance testing. I should (barring any disasters) have a 12-key keypad module within the next few months, and with a tad bit of luck a motor driver and temperature/humidity sensor right behind that. Matt has already announced his 16x2 Character LCD module and he said it should be out within a few months as well.

That puts us at 17 (15 if you don't count the power and breakout) modules by the end of the year, assuming Nwazet (or anyone else) doesn't release anything else.

Motor controller and accelerometer modules would be epic! The reason I asked because I was curious if delays were based on lack of interest from the industry.

From where I can tell its got a lot to do with the module builders more than anything else. Building a module is expensive. The Protomodule went something like this;
$300 R&D (doesn't include my time)
$200 Prototypes (6 of them iirc)
$700 First Production Hardware
$500 Assembly (had I not assembled them myself)

My total investment in time, blood, sweat and plenty of tears is in the multiple thousand dollar range.

For a product that still isn't widely adopted and which doesn't have huge marketing dollars behind it, that is quite a risk. I love the Netduino!Go, and I'll continue too build modules for it but I have to do it slowly. I suspect others are in a similar position.

Hi Bendage,

Are you still on par for releasing 'several dozen modules' this year?

Yes, that's definitely still the plan.

Building a new ecosystem is something that generally takes a bit of time, but we're off to a great start.

In the next few weeks, the GoBus ecosystem will have shipped at least a dozen modules and be working on the second dozen. Secret Labs has completed hardware designs for three new modules (SD Card, Ethernet, and a mystery module) which should be shipping soon. And we're currently working on the design for Ambient Light, XBee, and other modules.

Due to the amount of detail put into each module's design, it takes at least a few months to go from spec to shipping...but hopefully the end product is well worth the wait.

Nwazet and VariableLabs and Komodex are also continuing development on new modules in a public way, and others are working on modules behind the scenes (or for their own projects). I feel a bit spoiled because I have some of the new modules here to play with; I can't wait until everyone can get their hands on the newest ones.

[BTW, I should have said "within the year" rather than "this year". Most new electronics ship by October or early November...so some module launches may be held until early January lest they get lost in the holidays. We'll definitely be in the dozen to two dozen realm by the end of 2012, and we should move into the dozens as we move past the holidays.]

The reason I asked because I was curious if delays were based on lack of interest from the industry.

When we launched Netduino Go, we intended to wait a while and develop a full module builders' kit before bringing on lots of third-party module builders. Since there has been so much interest from both individuals and companies, we're currently balancing efforts between supporting module builders and getting tools put together for a simplified kit.

We're really excited about the enthusiasm that so many have shared about GoBus and Netduino Go. For us GoBus was and continues to be a long-term strategy, and it's great to see so much adoption in the first (less than five) months.

Thank you for your feedback; together we are making plug and play electronics for .NET a reality.

Chris

You also need to add that for modules such as sensors, displays etc. you will also need to allow for some time for software development for both the module and the NETMF driver on the GO!.

LOL Chris.. Mystery module!

I guess you don't call it secret Labs for nothin!

Please consider a 9 Degrees Of Freedom module. Guaranteed to sell the heck out of N-Gos with that one.

And you should also be able to do the Kalman filtering in hardware on the module too...

And it needs its own GPS module to provide absolute frame of reference so it doesn't get confused by a coordinated turn.

If you can get it to work at 200 degrees and 50G accelerations we can build our own space probe. There may also be interest from small countries with hard to spell names run by alarming people.
One day, all this too shall parse.

I think you'll find that any GPS modules available to the consumer will stop working above a certain altitude or speed for exactly this reason!

No, they are limited in height and speed, so pilots in small aircrafts (cessna and the like) can't use them for navigation.. They could probly work if limitations are removed, but they are not to be trusted since they are not made for it, and not tested for those conditions.

I was joking, Fred. I know about the limitations. Nes is right about the chipsets, except that anyone can buy them if you don't mind paying a premium with minimum quantities of 10,000. Of course, if you did that you would attract what might be described as scrutiny from people whose sense of humour has been surgically removed.

Domestic GPS chipsets use some assumptions about altitude to speed things up. If you invalidate those assumptions they will mostly work, but "mostly working" is not a phrase that pilots find reassuring.

Hi Mattster,

Can anyone comment on the theoretical maximum speed of the SPI bus?

Netduino Go can exchange data with GoBus modules using a SPI transport speed of up to 21 megabits/sec.

Simpler modules (like an RGB LED) will communicate at a slower speed, but more sophisticated modules (like the Ethernet module or Shield Base) can exchange data at speeds near or equal to the maximum.

BTW, communication is full duplex. So that's 21mbps simultaneously in each direction. ACKs are included in frame headers, so there is no waiting for dedicated ACK frames.

For STM8 modules, the fastest I've been able to go (while still actually handling and responding to messages, etc.) is about 650 kHz. Currently all of the STM8-based modules run at 325 kHz.

So I should be able to plug to NGo main boards together with a GoBus cable and get 21 mbits between them?
