1. Introduction
This note lists the matters need attention in each stage of designing and manufacturing while using MXCHIP module.
In order to achieve rapid mass production, application designers need learn this note first. Consider and avoid all
possible problems which may happen during designing, manufacturing, firmware programming and testing ahead of
time.
