Hadn't heard about this before. Looks like it had a cc3100 onboard.

Why can't I see the new Netduino 3 WiFi on the site? I see it at Amazon (ordered it already) and in the firmware package...

Interesting, looks to have three Go Bus sockets on the board as well.

What was that shiny new Netduino hardware seen in the keynote?

It's not officially announced quite yet, but here's one link that you might find interesting...

More to come :) Stay tuned!

So will the cost for a netduino up here in Canada be any more reasonable going forwards?  I just had to pay nearly $90 to get ahold of a replacement N+2 after smoking my last one, and if that's the kind of price premium I'm looking at (and this is WITH a discount), then the price premium of a Netduino over anything else is getting to be simply too much to be worth it.

Hi Sukasa,

Amazon.ca recently started carrying Netduinos--at roughly the same price as the USA. And Proto-Advantage typically sells for roughly the same price there in Canada.

If you can, please PM me more info about where you had the bad, heavily-marked-up experience... Thank you.

Does that help you out?

Chris

P.S. Some new Netduino gear will be crossing into Canada (for Amazon.ca) in two weeks.

Wow! That are great news :)

What means IEEE 802.11b/g/n exactly? Just 2,4 GHz support or also 5 GHz support?

 

Best...

We're pretty excited too :)

The CC3100R1 Wi-Fi radio is 2.4GHz.

Seems like it's available on Amazon now, but as always, Not possible to buy these for international buyers from Amazon.. 

 

 

I found two things interresting.. go bus ports.. And you have removed the Netduino Go..

 

So I guess support for Go is offically dropped now?

Given the prior announcement of upcoming GoBus modules, and that the N3W has the ports...  I wouldn't miss the Go if the advantages of it get rolled into the N3W.

Hi neslekkim,

Both Adafruit and Mouser have Netduino 3 Wi-Fi boards in stock, with international shipping. [If you don't see them in stock on their sites...just drop them a line.]

For international customers: the Netduino 3 Wi-Fi boards even have CE-compliant Wi-Fi radios :)

I found two things interresting.. go bus ports.. And you have removed the Netduino Go..

As we build up the number of available GoBus modules, Netduino Go will be an awesome choice for projects that need more than three modules at a time. We can only fit three boards in our 3-column hardware page, so we've swapped it out for now, but it's still in production, is fully supported and is going to get new firmware this week as well :)

Mouser have still expensive shipping, but I sent an email to adafruit, on the buy page on the product info, there are no mentions of Adafruit.

 

And things like this, how are they going to be used since one have to use other resellers to get stuff?

Forgot to ask, are the gobus ports on same channel?, or do we get the pleasure of three channels?

 

And RTC, I guess that is still not implemented here either?, the chip has it..

We'll add a link to Adafruit on the product's "where to buy" page as soon as the product is live on their site :)

For gift coupons and gift certificates: we will be launching an online gift shop on 30-Jun-2015. Including affordable USPS international shipping.

Hi neslekkim,

The three GoBus ports share one SPI transport channel. They each have a unique UART channel for module reflashing purposes.

And RTC, I guess that is still not implemented here either?, the chip has it..

There's no VBAT pin on the Arduino headers, so powering up the built-in RTC didn't make sense. If there are enough requests for this, we could make an RTC GoBus module (with coin cell holder) that auto-reloaded the time on boot. And for commercial customers deriving boards from the open source designs...we left the RTC crystal pins free :)

Full schematics are on the product specs page.

VBAT, I think it was discussed before, regarding go etc, Why do everthing need to be an arduino header?, look at other boards, no issue with adding an extra header?, or even pads to solder on, or even pads to add an cr2025/2032 batterholder on the backside... 

 

And gobus, there are 6 spi's on the chip, how many are in use total?

Doesn't seem like they have it, they said "Thanks for the product suggestion - we will share this with our teams. Please see our store for Netduino products"

 

bah..

Hi neslekkim,

One of the keystone features of the Netduino mainboards is wide electrical compatibility with Arduino shields. We try to keep things clean and compatible. I have seen some boards replace AREF with VBAT and other tricks...but these can lead to compatibility issues. And adding another header pin can confuse users.

If having an RTC battery backup if a big request, it's definitely possible to create a GoBus module to support that. Which would give us that kind of great RTC and VBAT flexibility without the complication.

All that said, we did leave the RTC crystal pins free in the Netduino firmware...so VBAT and RTC could be added without too much trouble in custom hardware designs.

And gobus, there are 6 spi's on the chip, how many are in use total?

Full schematic can be found here:
http://www.netduino....i_schematic.pdf

MicroSD gets a SPI bus. Ethernet/Wi-Fi gets a SPI bus. Pins D11-D13 get a SPI bus. And the three GoBus ports get a SPI bus.

We packed so much into this hardware that there are only three I/O pins free: a JTAG test pin (which we leave free due to an age-old STM32 errata) and the two slow crystal pins. :)

Look at how they have done it on these boads: http://www.seeedstud...uino-Stalker_v3

 

Ah, leaving the pins, so one can add some bodgewires is ok, I think on the Go it wasn't so?

 

 

Interresting, the schematic says the pins for rtc crystal PC14 and PC15 is reservec for the crystal, so that is fine, guess there is no pads though?

 

Also noted that VBAT is connected to VDD, so that means as long as the board is connected to power, the RTC should be fine then?

 

Does it exists better hires pictures of the board?, front and backside?

 

And there is no jtag connector?, to connect stlink or something?
