Hello.

 

I am wondering if it will be possible to make this RF 433mhz module work with Netduino.

 

Here is a link to eBay:

 

SI4432 470MHz 1000m Wireless Module 470M 433mhz Wireless Communication Module

 

could someone take a quick look and give me a hint

 

Thanks!

Yes, a quick Google search yielded a lot of results, including some Arduino specific ones. I have a weather station that transmits on the 433Mhz band and will procure one and work with you, if you want. I am using a Netduino 3 and Micro Framework.

 

Certainly worth a try at that price point.

Sure, i would like to work together. I also have Netduino 3.

 

For 433.92 I have a couple of indoor temperature/humidity sensors, several light switches (with and without dimmers), and a X10 based media remote control with USB dongle.

 

I also have a Tellstick Net that operates on this frequency and this is the one that actually bugs me since it is really hard to operate it on a lower level. Out-of-the-box it's possible to receive and send the signals through Tellstick only via their online service, so it's impossible to see the data that is being transferred and it's impossible to make a "no-internet" solution. This is the main reason why I am trying to replace it with Netduino + RF module.

 

As about the module, you will have to solder the pins (they actually are included in the "package" but not in the picture) and antenna to the board yourself. I was wondering, since the pins are tiny (1.27mm between them) and the standard jumper wires (2.54mm) will not "fit", what is the way of connecting?

Just in case, I have got the documentation from the seller, it's mostly in Chinese, and I translated the file names into English.

I have found some info about the module and how it is used with Arduino.

Converting from 5v to 3v using CD4050BE should not be a problem.

 

However the Arduino projects use RF22 library, and that could be a problem, I think.
