This article will continue detailing a minimal configuration design that uses an i.MX RT685 crossover MCU.    In the first article of this hardware design series, I introduced the power supply architecture of the RT600 series and illustrated some of the package/PCB layout features of the VFBGA176 package.       I also introduced some of the specs I am working towards for the “Super-Monkey” module and will power some of my future real-time audio processing projects.
