Hi @blackchart,
Unfortunately, all devices are sold out. Further production is possible only when ordering more than 10 devices (in this case, I also can modify the device to suit your needs).

I buy them on Aliexpress:

If you apply hot air it is easy to take off the white "double sided tape" and the plastic.

I highly recommend itead products, especially for those just getting into MySensors. They remove alot of the pitfalls that electronic noobs (such as myself) encounter when building their first sensor nodes. I used the RMini to build my first relay and it could not have been easier. Many of the troubleshooting problems posted on the forum have to do with setting up relays and these boards eliminate many of those issues.
I also recommend the nano shield from itead to any entry level electronics noobs for setting up early sensor nodes who are not ready for intricate soldering. It provides a nRf socket and a power jack and breaks out all of the nano pins with individual power and ground headers. Just plug in a nano and nRf and program from USB and power the entire setup through a single jack - perfect for beginners.
