Hello,

 

May I as a complete newbie ask for your advice?:

 

Today, I've bought the book "Getting started with the Internet of Things" from O'Reilly. Now I have to order the hardware but I don't know if should go for the Netduino Plus (1) or the Plus 2 version.

 

Will the book's hints, examples and projects work with the Plus 2 board, too?

 

Thanks in advance for any helpful hints.

While either should work fine for that book I would go with the Netduino Plus 2. In just glancing at the spec sheets a few things stand out.

Hi Frankinho, The book should work well with the new boards as well. Just be sure to add the "SecretLabs.NETMF.Hardware.AnalogInput.dll" to your project and use the full namespace in your variable declarations. The same goes for "SecretLabs.NETMF.Hardware.PWM.dll". Of course you're welcome to pick up one of the first-gen units (at a bit of a discount) as well...and they'll work without the extra steps. Chris

Thanks to you both.

I've now ordered the NP2.

 

Btw, obviously the book's author has provided some updates of the sample code on his website for the book, as I've found out in the meantime: http://www.gsiot.info/download/ .

 

I'm looking forward to the delivery of "my" NP2, which I had to order via one of the European distributors mentioned on this site here.

Thanks again.
