RFM69 Nodes w other form factors & power options

[Joshua]

Howdy,

I'm going to play with some different power sources and form factors starting with a simple door/window node. There will be a mix use of reed or hall sensors and CR2032 and 16340 batteries.

Check out this little gem.. By the looks of the spec, there is no need to change the code. Button Sized RFM69 Wireless Nodes

Aside from any regular reed sensor, I've read that this hall sensor may be a battery efficient candidate. S-5712ANDL2-I4TlU

Everything is ordered and I'll update this thread as I move through the build.

papa: Good to hear from you, Joshua. This node, etc looks interesting.
    I look forward to your documenting these.

Quick update!! I ordered 2 of the Button Sized RFM69 Wireless Nodes that just came in last night.

I loaded the RFM69 node sketch with SWITCHIRQ enabled with a RF69_915MHZ radio (IS_RFM69HW disabled). It came on right away with no issues. This weekend, I'll build out a little door monitor case and test with a simple reed switch powered by a CR2032 battery. Initial though are encouraging. Initially, two changes I would like to see are:

• the width of the board to be a bit wider to all for breadboard prototyping and PCB installation. However, I should move past this as a PCB will increase the footprint of an already small size.
  
• pin-out diagram. The text is super small.
  

Here are some photos with the button nodes along side a Pro Mini

papa: Thanks for an encourage update on this product, Joshua.  Keep it coming.

I went ahead and posted a new build here at Josh's thread on RFM builts and 3D cases

Next time, I'll purchase www.tindie.com/products/easySensors/button-sized-rfm69-wireless-node-ver-2/

There is another, cheaper, board and radio here Anarduino and it appears that the radio is wired in the same as ours as well.

Papa:  Yes, the Anarduino Miniwireless is a small board that can include an RFM69 radio, extra memory (helps for over the air programming), & a real time clock.  It can work well for much of our node projects.  I've written some threads documenting them including over the air programming & a mail box node.  One needs to use something like an FTDI board to program it at least the first time.
