@korttoma yes i use the pro mini 3,3V but can Ireplace the Radios simply with a modification of the Sketch ? Because hen I Flash following Sketch to the Easy pcb:
// Sample RFM69 receiver/gateway sketch, with ACK and optional encryption, and Automatic Transmission Control
// Passes through any wireless received messages to the serial port & responds to ACKs
// It also looks for an onboard FLASH chip, if present

I get following result:
Listening at 868 Mhz...
SPI Flash MEM not found (is chip soldered?)...
RFM69_ATC Enabled (Auto Transmission Control)
well, I have a 10uF electrolytic there. Hope it makes not the big difference. On the boards with NRF works that fine so far.
will try it.... -> Learning leasson...
