This is to ensure as stable operation as possible.</p> <p>The most sensitive part of the layout would be at the RF output as even small changes can severely affect performance and range. You should also ensure a good connection between ground and center-pad, preferably with vias underneath the chip.</p> <p>You should also avoid routing traces underneath the XTAL crystals.</p> <p>If you have a layout or schematic design you want us to review feel free to create a DevZone case with your project files, or images of your design. If your design is confidential you can create a mypage case at <a href="http://www.nordicsemi.com/">nordicsemi.com</a>.</p> <p>Best regards</p> <p>Jørn Frøysa</p><div style="clear:both;"></div>
