Taking a detour from my Outdoor Mic series, as I have a new toy that’s arrived in the mail: an i.MX 6ULL evaluation kit. Here it is on my desk: I’ve taken a run at an embedded linux project bef...

As I sit down again to work on more PCB layout, this is where we left things: …I feel like I was further along. Anyway - I’m just going to go through piece by piece. Random Components R4, R5,...

Early Layout Switching over to the PCB tab after a bunch of time in the schematic is always a bit of an initial fright, since it just lays things out in a giant line: But this isn’t too hard to...

Picking up where I left off in Part 5, I’m going to continue to add components to the schematic for the MCU breakout board. My goals are to get the ethernet PHY and RJ45 jack added, and then add s...

The First PCB Mistake All of the needed components, the PCBs and the solder paste stencil have arrived and I’m ready to put these together: Something doesn’t look right, though…what’s wrong wit...

Introduction The PCBs, stencils, and components for the microphone breakout that I ordered in Part 4 have all arrived, which is exciting, but I don’t have time at the moment for doing assembly, so...

Introduction Cool, isn’t it? Now that our first board is on it’s way - OSHPark says that it will be back from the Fab in a day or so, and then it’ll be a few days to arrive via the (free-shippi...

Introduction In Part 2, we finished picking out all of the major components for our outdoor, PoE-powered microphone project. In this part, I’m going to walk through the next steps that I like to ...

Introduction In Part 1, I outlined what we’re building, and the first steps in turning this into something real - picking the major components. These include: The microcontroller, which will ...

I decided that I wanted to get some writing down on a walkthrough of how an intermediate amateur goes from idea to execution to delivery on a PCB design. This is the kind of thing that I wanted to...
