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

Nice design! Are you happy with the NRF24L01(SMD) or did you experience any range issues?
-
I really happy with smd version from nrf24l01. Cuz i use as gateway a very old nrf24l01 (2 years ago got at ebay) with a green PCB and 10 pins.
After flash a test prg, it comunicate with this old chip. The range ... hmm, i have no idea. All my prototypes are at the worbench now. But i'll make a small rangetest at the weekend.
... make a better photo in next day's

My experience with the smd range very similar to the usual nrf modules.

Here some better Pics from Prototype:

Here with installed HML5883 Magnetometer, but sadly doesn't work.Don't know why, but i decided to rework the design and replace all I2C sensors with a Solarcharger/Supercap-PowerSupply and add a voltage booster for 5V.
