14.PCB Layout Recommendation
14.1 Antenna
Antenna trace impedance should be adjusted to 50ohm.The area above (or under) the RF antenna trace
should be free from other traces.
15.0 HCI UART Lines Layout Guideline
The following HCI line routing must obey the following rule to prevent overshoot/undershoot, as
