You can use three different Transceivers:

• RFM70 or NRF24L01(SMD) with mysensors.org library
• RFM12B or RFM69X with jeelib library

The PCB are shared at oshpark: https://oshpark.com/shared_projects/ezK4aEQd

And here some Features:

• use a normal Arduino mini pro as stacked interface
• optional you can add Magnetometer HML3358 and/or SHT21 (Temperature/Humidity)
• powered via coincell CR2032
• small Footprint (25mm x 41mm)
• holes to screw on a enclosure
• extra pins for D2 - D9 for ur external sensors
• extra I2C pins
• Flash for OverTheAirUpdate’s

Some Features are not testet now, but i will publish some news about this Project here.

You like it? You want some more Informations?

Ok, write here in this thread

I use a lot of mysensors nodes. This looks like a great pcb. What if you want to use a 5V pro mini? Is there place for a 3.3v regulator?

@sweebee Thank you, no i use a Arduino Mini Pro with 8MHz and 3.3V Regulator. Sure i have to cut the Power LED and remove the regulator on the ProMini to work together with a coincell. The mini are stacked on this PCB, save a lot of work with soldering

I’ll make a better pic this weekend

Here some better Pics from Prototype:
