@GertSanders Thanks! :)
@shabba I've almosted completed new ultrasmall radionode based on rfm69. I'am very busy now but I hope to finish all tests in a week. I will post board asap :)

oh maybe I didn't understand well, I thought that semtech ic (rfm69) would be onboard?? because if we wire our antenna, I don't see well why not use rfm69 module instead. In case of pcb antenna trace, ic onboard makes more sense imho. but maybe I'm wrong..I thought to give a try to this sometimes ago but had this reflexion,..and good design of pcb antenna trace for 433-915mhz is a lot bigger than 2.4ghz nrf. and smaller trace, lower range..+ need to be tuned for each design (in theory, I'm not expert)
that's cool because koresh is skilled at this :) lot of thing to learn! so I can't wait to see or try one board! -
Hi,
I got all the parts, but I think the NRF24L01 is the normal version and not the + version, there is no + to be found on the chip.
Would the older NRF24L01 ( without plus ) work on the board ?, or do I have to use the R1 resistor ?
( Resistor 1M ( which package size ) - unnecessary element (R1 can be mounted for backward compatibility with nRF24L01, nevermind)Alex

Ermm... how do I know it works correctly ?, and if it doesn't work correctly which 1M resistor do I have to use ?
Thanks for your help !!!

@Slorf NRF oscillator can work or not (or could stop after some time). If problems appear use any 1m resistor (0402 or 0603 if you can solder it). Do not worry. It is the last stage (after nrf soldering and atmega programming).
Can you provide link to your nrf chip(where you buy it)? I want to check it. -
Sorry for the late reply, our second son was born just 2 weeks ago.... no sleep anymore :-)
It looks like this one, except mines it labelled: 0935VI, the one on the link 0935VJ

@koresh Just created a light sensor from one of the boards I bought from you. It works great !
I had to do some tweaking with the serial monitor speed from my arduino IDE (I had to double the speed which was set in the code or something)
I also had to press the reset button just before uploading of the sketch started.
Apart from that: Great !

Thanks !@Sander-Teunissen
Thanks to your responce.
I'm sorry to hear you faced some hardware problem. Of course the board must restart itself. It may be couse of low quality of mounting first boards or it was damaged during delivery :(
May be you used incorrect usb-ttl converters boards without correct dtr line? I faced them year ago.. it was bad surprise ) -

@Koresh I guess I already know the answer, but this board works with 3.3 volts ? If I want to connect something like this:
https://www.mysensors.org/build/motion ,which works only on 5V I'd need to add a step up converter ?Sander.

Board contains two 3.3v LDO. You can change one of them to 5v (do not forget check schematic).

@Sander-Teunissen you can modify the motion sensor to work on 3.3V (see http://www.instructables.com/id/Convert-a-5v-PIR-Motion-Sensor-to-33v-for-ESP8266/)
