PCB Design Overview

2.1. Footprint and Keepout Area


A 4-layer PCB is strongly recommended.
 First, check whether the module's footprint is of the latest version provided by Quectel. For specific
footprint of each module, please refer to document [1], [2], [3] or [4].

Do not design pads 73–84 and do not route the keepout area with any traces or copper.
