One early decision can push your entire hardware project in the wrong direction, and you might not realize it until you're months in and things start falling apart.

That decision is choosing your microcontroller.

Once that part is locked in, everything else has to bend around it.

Your firmware structure, power behavior, wireless options, certification path, and debugging process all get shaped by that single choice.

So in my latest video, I walk through the ten most common mistakes I see when people choose a microcontroller.

Top 10 Mistakes When Selecting a Microcontroller (MCU)

You'll learn why weak tools and thin documentation can turn every bug into a long investigation instead of a quick fix.

I explain why picking an MCU (Microcontroller Unit) right at the edge of what you need almost always backfires when the product evolves.

You'll see why more CPU performance often makes things worse, not better, especially for battery life.

I cover how memory that feels "plenty" in early firmware can disappear fast once features, logging, and security requirements start stacking up.

I share why picking the MCU before defining your system architecture forces compromises that didn't need to exist.

And you'll see why supply and lifecycle planning might be the most important factor of all, because if you can't build consistently, everything else stops mattering.

So if you're in the early stages of product development, this one could save you months of painful rework.
