My new RP2040 test board so I can use the chip in my own designs.

It’s not much but it works and I made it.

After reaching a goal of being able to mill for QFN56s with a 3020 CNC, I made this RP2040 board as a proven template for larger projects.

Two firsts for me this go around were external flash and 16 pin USB-C with data transfer, which was almost as difficult as QFN. It’s only been micro USB in the past.

Other than that, it’s got a user LED, and addressable LED and a tiny potentiometer for testing the ADC.

Oh, and it’s got a reset button😉

I got a lot of cool ideas cooking now I have this and a proven ESP32-S3 template.

Two firsts for me this go around were external flash and 16 pin USB-C with data transfer, which was almost as difficult as QFN. It’s only been micro USB in the past or 6 pin USB-C for power only.

Two firsts for me this go around were external flash and 16 pin USB-C with data transfer, which was almost as difficult as QFN. It’s only been micro USB in the past or 6 pin USB-C just for power.

First homemade ESP32 dev board with an SOC

First try building my own test dev board with the QFM56 ESP32-S3 SOC. Milled and assembled at home.

The mask didn’t turn out that great but it uploads, blinks and prints.

Been working really hard towards this. I have so many ideas of what to build.

I’m so happy 😃

Just got a cool project working? Want to turn it into a PCB but don’t know how yet? I’ll do it for you.

To celebrate a long awaitedmilestone in my embedded systems learning journey, I’d like to help a few beginners turn a working breadboard or perfboard project into a real PCB.

Ideal projects:

-Already working on a breadboard or perfboard
-Simple hobby electronics (LEDs, sensors, displays, small robotics, Arduino/ESP projects)
-Low-voltage circuits
-Under ~20-30 components
-You’re interested in learning to or have the ability to solder the finished board

What I’ll provide:

-PCB layout
-Gerbers and manufacturing files to you can send out to have your PCB made.
-Assembly notes where appropriate

What I’m looking for from you:

-A description of the project
-Photos, schematic, or wiring diagram
-What you’ve already tried

Reworks only if a mistake is made on my part so make sure you know it works first.

I’ll only be selecting a small number of projects so I can keep this manageable while continuing my own learning journey. At least 3. I will pick projects:

This Saturday morning

Next Wednesday evening

Next Saturday morning

Who knows, if I see something that really catches my eye, I might pick more at other times.

I’ve learned a lot from the Arduino community over the years, so this feels like a fun way to give a little back.

Looking forward to seeing what you’ve been building. Thanks for helping me celebrate this milestone!

Finally got my QFN milling from operational to optimal

Celebrating a mile stone.

I finally did some fine tuning on my 3020 CNC and endmill profiles in FlatCAM and milled the best board I ever milled.

I used to have to keep my traces .3mm and above. Anything lower risked disappearing. I only recently was able to get small, low pin count with relatively high pitch working. QFN56 like this ESP32 SOC with .4mm pitch was out of the question.

Now I can reliably make .2mm traces and any QFN I want. Beautifully.

Long time coming. So worth it.
