I'm designing an RF remote control based on the FRDM-CR20A board design. The initial tests have been done with the FRDM-CR20A board and everything has been correct. I have exactly copied the design of the Gerbers and I have used the same components to make my board. But once manufactured and assembled, I see that the emission frequency moves to the next channel. Code is correct, it is a hardware problem, could you give me some help?
Thank you very much in advance.
