New nrf24l01+ smd
-
@alexsh1 yeah they are not really new and well.. as you said, for smd mounting.
Here you can see the pinout: http://www.sunrom.com/media/content/404/dim.gif@Oitzu I did not realise they are not new. However, my point is that I'd to know how these perform vs normal ones.
Also I can fit them into a very tight places. However, getting 0.05" (1.27mm) headers is a problem. Will be ordering some on aliexpress shortly if I manage to find them.

@alexsh1 mounting the SMD version of the radio with wires on the Sensebender would really make it small
From browsing OSH Park, I believe @GertSanders is experimenting with the SMD radio also (sorry Gert for lifting the lid) ;-)
-
@AWI Thanks - really great to know that @GertSanders has been already working on a SMD version.
I found another interesting adapter for 1.27mm nrf24l01+

By the way @GertSanders , is your SMD board similar to @m26872 one (http://forum.mysensors.org/topic/2067/my-slim-2aa-battery-node)?
-
Propably no difference. I have asked about it a week ago http://forum.mysensors.org/topic/2984/nrf24l01-mini-vs-normal-size-module

@AWI No problem, this board is making its way to me via the mail now (was shipped from OSH Park last wednesday).
I'm hoping to test it coming week.
This board one is a one-trick pony. It is based on @m26872's concept of a very narrow board, but in my case I just need it to handle 2 magnetic switches. So pull-up resistors and connection for two contacts (normally closed) is provided (on the pins that allow hardware wake up from power down), and nothing else. No crystal, just minimal power decoupling and a led. No FTDI adapter or ISP. And of course only connection for the SMD version of the NRF24.
While that was being made at OSH Park I prepared a second design, but this one is still in movement (not ordered yet), measurements are in mm:
It is certainly not a Sensebender, as it lacks ATSHA204A, SI7021 and SPIFlash, but it does have FTDI interface and optional pull-ups on D2 and D3. It is my first try at SMD, with 0805 size components (I need to be able to hand solder them).
The objective is to make a working sensor board as flat as possible. At the moment is is even smaller then the CR2032 batteryholder I was planning to use. A possibility is that I go for a two board approach using this "flat node" and a second board to hold a CR1632 (a holder for this smaller battery is in the image above, Keystone Technologies model 3013).
To be continued ...

This is what I was looking for as I need a small board for a reed switch. Please keep us posted about your testing
