Re: Is the DAUGHTER CARD a product that is sold separately? (PIC32MZ DA Starter Kit)
For what it's worth, I have always regarded those 'starter kits' as doing two things for me:
1) A 'known good' hardware platform on which one can learn the process of writing applications and getting them flashed to a target
2) Plundering the hardware schematics to discover all the things they don't tell you in the datasheet. A prime example: Unlike other Microchip processors I've worked with, the PIC32MZxxxDAx requires an external 1.8V voltage source even though reading the datasheet that's not at all obivous (to me, at least) so for me, the big fat clue was the additional Vreg on the starter kit!
Once you're past those two points, I generally find you need to start interface to the bits and bobs for your application, and therefore spinning up a 'best guess' printed circuit board is desirable. I usually start with one of the $10 horrors from one of the Chinese or Indian PCB manufacturers, so the outlay is modest. Admittedly for me, that's easy, as PCB design is something I've been doing for decades. If you have to pay somebody to do it, the economics might be different.
