3.1 USB Evaluation Kit Schematic

Placement Difference for C4, C5, R1, R2, R3, R13 and R16:
due to different functions: UART or Direct USB
UART / Direct USB // The different variants are seperated by backslash. Left side is for UART, right side is USB direct.

Antenna "Keep out Area"
Do not place any ground plane under the marked restricted antenna area in
any layer! This would be affecting the performance of the chip antenna in a
critical manner.
