How to Successfully Integrate a Wireless Module
Published on February 15, 2022
Choosing the right wireless technology for your design is always the first step, but this decision is influenced by many constraints like required range, data rate, battery life, security, infrastructure, signal coverage, product size, co-existence, knowledge, time frame, and more.
The design recommendations in this white paper mainly cover the placement of a module on a circuit board, module placement with respect to ground plane, and routing of crucial signal traces. Recommendations are also made regarding more general issues like power supply or handling of special purpose module signals.
We’ll browse through several design topics. We will not dive deeply into antenna and RF theory here but will provide some basic information to shed new light onto and motivate the design recommendations from the module datasheets.
