P9038 LAYOUT GUIDE
AN-894
Connecting a Power Source
The USB input connector accepts micro-USB cables type A or B. If a new design does not need this connector, simply extend
the VIN power trace and GND as needed to the location the new power connector will be placed at. If moving the power
connector is necessary, it is suggested to keep a solid GND plane leading to the new connector location and route VIN at a width
that is at least 100 mils wide as space permits.
Connecting Inputs / Outputs
All input and outputs on the reference board have been placed near the edges of the reference layout such that they can be
easily connected to other parts of the system board. After placing the module in the specific design, use the labeled vias as
connection points for new traces on either the top or bottom layer.
Manufacturing Notes
PCB should be made with a minimum of 1oz copper foil weight per square foot or heavier.
