(I ran out of steam for now, will return over time. Glad to have help in filling in details, fixing errors, and suggested additional options)

There are a number of very interesting designs here, and I thought it would be worthwhile to list them, because I start getting confused and others might as well.

The following are Arduino ATMega compatible using the Nordic nRF24L01+

In the following , APM = Arduino Pro Mini, Nano = Arduino Nano, nRF = nRF24L01+ module

---

First, let's mention the approach documented in the how-to here, combining cheap standard Arduino family boards with the radios.

• 3.3v APM @ 8Mhz (150ma 3.3v) directly connected to nRF
• 5V APM @ 16MHz (150ma 5v) with adapter board and reg to connect to nRF
• 5v/3.3v Nano @ 16 Mhz (150ma 5v, ?? ma 3.3v) directly connected to nRF

In this case, you add whatever sensors you want externally. The APMs use a ceramic resonator, not sure about the Nano.

@axilent http://forum.mysensors.org/topic/179/mysensors-battey-board-revision-1-0
3.3v MySensors Battery Board Rev 1.0 ATMega328p @ 8 Mhz

Power::

• 0.7-x.xV boosted to 3.3V @ xx mA by TPS61222DCKT
• Onboard single AAA holder, externally use 1-2 AA or AAA or whatever
• solar input connector 0.8-5.5V and solar will be the main power while solar voltage is higher than battery

Radio: onboard nRF24L01+ chip and antenna

• CE/CSN/IRQ: @ D8/D9/D7

Sensors/Actuators:

• Temp: TMP102AIDRLT accuracy ± 0.5 ° C range -25 ° C +85 ° C with MCU wake up function on alert @ I2C
• Red LED @ D4

Connectors:

• 3 GROVE connectors (D3+D4, A0+A1, I2C=A4+A5) each w power/ground
• ICSP (MOSI,MISO,CLK,Reset) w power/ground

Size: 50x50mm

Highly optimized for low power. Uses internal 8 MHz RC oscillator. This differs from the rest in that it has the nRF24L01+ chip directly on board (including "?" style antenna) rather than having a socket for nRF module.
"it can run until discharge to 0.7V regardless of frequency'

Price likely $15-22 populated, not yet available.

SeeedStudio DevDuinos http://www.seeedstudio.com/depot/s/devduino.html?search_in_description=0

3.3v ATMega328p @ 16Mhz
Power:

• CR2032 (v1.3) or
• 2xAAA (v2.0) onboard holders

Radio: 2x4 socket for nRF module

• CE/CSN/IRQ:

Sensors/Actuators:

• Vin voltage divider @A2
• Temp: analog MCP9700 (-40 ° C +125 ° C, accuracy of ± 2 ° C) @ A3

Connectors:

• 3 GROVE connectors (D2+D3, A0+A1, I2C=A4+A5) each with power/ground
• ICSP (MOSI,MISO,CLK,Reset) with power/ground

Size: 30x40mm (V1.3), 30.5x67mm (V2.0)

nRF modules hang over the PCB (may interfere with GROVE connectors on V1.3)
"it will work until discharge of a cell to 0.9-1.65V (supplying 1.8-3.3 V) depending on the frequency used"

Price $17 populated, including nRF module

Nice! Just want to mention that my design has two connectors. The 5 pin one you mention, as well as a 3 pin one that breaks out D3.

About the;
SeeedStudio DevDuinos http://www.seeedstudio.com/depot/s/devduino.html?search_in_description=0

Has anybody tested it with the mysensors vera gateway?
Does it work?
For a newbie like me it is attractvive as it requires minmal soldering activities/knowledge

Thanks for your feedback

APM = arduino pro mini

Keep this post updated...please :+1:

@funky81

See the link near the top of the (edited) original post, to a thread which follows up on this one. For board designs created by the community, that thread going to be more up to date (and it tracks some information about what's available).

This thread was earlier, but lists commercial options as well, so it's still of some value.

I'm thinking to let the other thread keep up with community designs, but if you know of a good commercial offering for our purposes, please leave a reply and I'll add it to the list here.
