Using the Newest gen ARM, Part III

The continuing saga of the 0.4 mm pitch KL03 ARM microcontroller. If you haven't yet done so, read part I, and part II. Today, I have a look at the good, the bad, and the ugly - or more accurately,... Read more

USING THE NEWEST GEN ARM, Part II

I'm a bit behind in my blog work - well, way behind, actually. I started this series back in January with the intro post. Here's where I am right now: I have three different sets of PC boards. One set,... Read more

Using the Newest gen ARM Microcontrollers

I've written a few times about the new Freescale KL03 ARM Cortex M0+ microcontroller. This particular part comes only in very small packages, with the smallest being a 1.6mm x 2mm WLCSP (wafer level, chip scale package) 0.4mm pitch, 20... Read more

Polarized non-polarized components: Inductors

We have a number of manufacturing engineers running around here at Screaming Circuits. They're very good at what they do, as are our operators and technicians. They are not, however, electrical engineers. Our parent company has a big group of... Read more

Do you Need that Part? Or, is it Just Habit?

At the moment, I'm working on an Arduino compatible clock. Like most of my Arduino compatible boards, this one uses an Atmega32U4, with USB built in. With the Atmega32U4, I sacrifice a little in program memory and SRAM, but gain... Read more

VTP - Very Tiny Parts

A while back, I wrote about a new ARM Cortex M0+ chip from Freescale. It's not the first M0+, but I do believe that it's the smallest. I've been checking stock off and on and finally found the smallest package... Read more

Cost Reduction in Design - More Advice for Makers

As a Maker, you really need a decent price, with good quality, and good service. Contrary to what many people think, you don't need to look outside of North America for this. You can keep your gaze West of the... Read more

Unsolicited

I have a question for you. When is the last time that you responded to an unsolicited email? It's been a very long time for me. However, I just did open up and read an unsolicited email that actually seems... Read more

BOM process

All of this talk about BOMs these days, (all of my talk, that is), kind of begs the question of how BOMs are put together. An Excel spreadsheet seems to be the most common "BOM management" tool in use today.... Read more

To Mod or Not to Mod? That is The Question

Many years ago, I was a product manager at a business-consumer electronics company developing some pretty leading edge display equipment. Prototyping back then was a long and painful process. A PC board might take a month or two to arrive... Read more
