Board Layers - Semtech TSWIRX-LI-EVM User Manual

E. Board Layers
The TSWIRX-LI-EVM PCB is based on a four layer design as shown below. The ground plane in layer
two is recommended to reduce noise and signal crosstalk. The EVM placed all components on the top of
the board for easier evaluation of the system. End product versions of this design can be made
significantly smaller by distributing components on both sides of the board. The Gerber files for this
artwork can be downloaded from the Semtech web page.
