What was that shiny new Netduino hardware seen in the keynote?It's not officially announced quite yet


Sorry to spoil the surprise. I blame Hanselman. I am at BUILD this year.

Hi neslekkim,

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

If you really want to hack it, you could certainly wire up an RTC crystal (and caps) directly to the MCU pins... But I wouldn't recommend that for the less-brave-at-heart. And yes, you could deliver power via battery--but you're really not gaining much unless the MCU is in sleep mode. [You can already keep pretty accurate time just running off of power.]

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

We can take some more photos. There are also some blog posts out there already from folks who already have a Netduino 3 Wi-Fi in hand (or photographed one from the lab at BUILD).

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

Oh yes, one of the details I couldn't fit in the announcement: there are SMD pads for a MiniJTAG header on the back. That's a new standard feature, and is how we debug the boards' firmware ourselves. By putting it on the back, we were able to bring back the ICSP headers for compatibility with even more Arduino shields.

No worries. It's fitting that the guy who helped inspire the new hardware helped spoiled the surprise :)

Did you happen to get any photos of the Netduino 3 Wi-Fi lab from BUILD? [With the new NETMF APIs, weather shield, and Azure connect the dots?]

The reason for RTC is that it gives interresting possibilites for wakeup, one can make the mcu wakeup on given times/dates.

Take a look at TagConnect next time, then one don't need to solder an connector, just press an connector with pogopins.

And what about MakerShed? I can't recall how Microcenter obtained both of the earlier versions that I selected, but that's where I bought them.

More resellers, both US-based and international, will be coming online this month :)

If you have a favorite Netduino reseller, please let us and them know you'd like to get your new Netduino from them.

Anyone that can ship with reasonable prices to Europe. I kinda prefer to buy from Adafruit or Proto-Advantage since they have reasonable prices and shipping costs, compared to European resellers.

I supplied the images for the demo app Jon wrote :)

Hey Pete,

It was great to see the NETMF side of Microsoft IoT represented at //build/--including in the keynote.

We'll "blame" you for the demo app images--in a "let's everyone virtually hug Pete brown" kind of way :)

Thanks for all your enthusiasm and support!

Chris

At least one of those resellers will have stock this week, with a little luck.

Amazon.com has been having some stock shortages, but we are fulfilling inventory out of at least five warehouses--so that is hopefully clearing up quickly. And we should have inventory at Amazon.ca and Amazon.co.uk soon too.

You couldn't see it, but the robot that Colin controlled with his phone in the maker video, runs a Netduino board. I don't recall what version.

 

The maker video will be up soon (we couldn't upload it yesterday because someone else ripped it from the stream, and YouTube is saying our official one is a duplicate. We'll take care of that tomorrow.). In that video, colin also made some specific statements about where NETMF fits into the bigger picture.

 

Steve also had NETMF photos in his maker session, including Gadgeteer and Netduino 3.

Hello!

I just did in that one. Micro Center for direct sales, and online being Adafruit (Not that I buy my Netduino gadgetry from them) , I use them for the strange stuff that the stores are slow to sell direct. And finally MakerShed.

 

So there you go.

I've been sedentary on the Netduino front .. I like my original model but haven't really done anything with it. I hopped on the website and saw the model 3 (w/ WiFi) and purchased it from Amazon (should get this friday, three painfully LONG days away). I am eager to see how the WiFi works.

 

Is it possible to control the WiFi client settings realtime from the C# code? Or is it something that is configured while updating the code? I'd like to see the ability to have an SD card with application settings (for the project I have in mind) that also include WiFi settings and then at boot time, have the SD card read and WiFi configured/connected.

 

Lastly, it would be nice to have Adhoc or WiFi AP mode, but I am 99.9% the WiFi was a "near" direct replacement of the Ethernet hardware for (WiFi) client purposes only.. Not a BIG deal, just be cool in my opinion.

 

I look forward to tinkering and getting back into embedded hardware after a 2+ year (almost 3) hiatus.

Hey Doug, welcome back!

I'd like to see the ability to have an SD card with application settings (for the project I have in mind) that also include WiFi settings and then at boot time, have the SD card read and WiFi configured/connected.

Right now you need to configure your AP settings using MFDeploy. We have had a few requests to enable changing the SSID, passphrase, etc. from C# code--and are working on a short-term solution to enable that for you guys :)

[With NETMF 4.4 and beyond, we are trying to deprecate a lot of the older SPOT code and so we're a bit hesitant to implement a Microsoft.SPOT.Net namespace-based solution...but I want to make sure that our community members can accomplish their project goals.]

Lastly, it would be nice to have Adhoc or WiFi AP mode, but I am 99.9% the WiFi was a "near" direct replacement of the Ethernet hardware for (WiFi) client purposes only.. Not a BIG deal, just be cool in my opinion.

The CC3100 chip does have the ability to serve as an access point for one device. That's not implemented today--but could be added in the future. I agree that that would be cool. [I have a feeling that we need a UserVoice-like site to vote on new feature requests.]

Chris

P.S. Netduino 3 Wi-Fi uses the new hybrid Netduino.IP stack--which is a managed code stack. So if you want an extra weekend project you can actually implement things like the change to AP mode by modifying the core code. Source code is at https://github.com/n...nkLayers.CC3100

Hah.. fast turn around on the question... Nice.. it can have AP support.. SLICK!

 

I was looking at the schematic: http://www.netduino....i_schematic.pdfand wondering why there is a ground on both sides of the antenna? (J13 AH316M245001-T -- in particular PIN 1 of J13) . I need to look up the DS on that to see their reference implementation and that will probably answer my question.

 

As for deprecating older "SPOT" code, since I haven't written any code against that (not even sure how too), it won't hurt me -- but I don't want to speak for the community that depends on that code/API and get them angry at me for pushing newer functionality at the cost of existing working code. I guess having the ability to switch between NETMF 4.3 and 4.4+ will be an issue for some.

The antenna is actually two parts: the chip you see and the part of the chip that extends to the ground plane (surrounding by PCB stapling). The antenna feed signal is technically connected to the part of the antenna which is part of the PCB.

I guess having the ability to switch between NETMF 4.3 and 4.4+ will be an issue for some.

Code reuse and code compatibility is an extremely high priority for us. So while we'll be supporting use of the new Universal API-derived APIs you will not need to rewrite your code.

Was the Netduino 3 Ethernet supposed to be available now?
