5. PCB Layout
Usually, most electronic products with good performance are based on good PCB layout. A bad PCB layout will
lead to lots of issues, like TDD noise, SIM card not be detected, etc. the final solution for these problems is to
redo PCB layout. Making good PCB layout at beginning will save develop schedule and cost as well.
This section will give some guidelines on PCB layout, in order to eliminate interfere or noise by greatest degree,
and save product development period.

Pin Assignment
Before PCB layout, we should learn well about pin assignment in order to get reasonable layout with so many
external components. Following figure is the overview of pin assignment of the module.
