Vertically mounted Arduino for Breadboard

This is an Arduino-compatible, vertically-mountable microcontroller board made entirely of TH components

I personally love the concept of electronic boards connected in "slots" (vertically attached to a horizontal board), like most industrial-grade PLC's or even our desktop's expansion cards (video, sound memory): it saves a lot of space and adds more functions to the system, all at once!.
This is yet another Arduino compatible stuff, but with an interesting difference: it is meant to be vertically mounted to a breadboard or PCB, different from the Arduinos we see out there (that you attach horizontally to the breadboard or PCB).
The schematic diagram is based on the Arduino UNO schematic diagram from website, except that I have removed all USB-to-Serial circuitry, making it more like an "Arduino Pro Mini" compatible.
I tought this concept might be interesting to breadboard prototipying, since it doesn't spread components all around the breadboard and also does no occupy both sides of it.

Basically what I did was download Arduino UNO design files from the website and strip down all parts and circuits I didn't need; I also replace most parts for similar/compatible ones from Adafruit/SparkFun/SeeedStudio Eagle CAD libraries.

My final goal was to creat an all-Through-Hole (TH) board that could be assembled by virtually anyone with a soldering iron and some will to do it.

The result of this work would be (I tought) an Arduino-compatible (vertically)- attachable prototipying board for breadboards or final products.

I just received your board. I see that there are five components listed and I know where on the board they go but the board contains many other connections for other components. What are they for? Can I leave them disconnected?

Hey, what a good news!. Look at this image: (
) there are 6 resistors (R1..R6, all 1k), two 22pF capacitors (C1, C3, for the cristal), 4 100nF capacitors (C2, C4, C6, C9), two 10-47uF capacitors (polarized). The top-right 6-pin connector is ICSP (same as Arduino UNO) and the 6-pin header by the side is for serial communication (USB-serial converter). If you have Eagle CAD installed, you can open the .sch file available here:

Awesome work! 

Ive been doing the same for years but with PICs (not trying to Hipster/hate).

Its an awesome way to prototype and im glad to see other people reaching the same conclusion.

Thank you! that's true, vertically mounting PCB's on onther PCB is not a  new concept, and I'm impressed to learn that so many people are still into it. Thank you!

I love this idea, absolutely brilliant.

This is great.

I'm currently working on a project that has components mounted in a DIN enclosure that I am struggling to fit everything in. a Vertical mounting board is a great idea!

That's true, with the horizontalization of things (board) people sometimes forget the can be put in vertical as well ! hahaha

  Are you sure? yes | no

Craig Hissett wrote 03/07/2016 at 16:34 point

Ha ha!, It's more the way vertical and horizontal can be place side by side in perfect harmony that I most admire :)

I just did exactly same thing for ESP-12 module, as existing breakouts are not usable on single standard width breadboard.

Vi o seu post no HAD e bolei um também: #SILSpark

Nice work, I'm glad to inspire people on their own hacks!. Followed you and will be looking for progress on your project.

Good effort!! Although I doubt I'd use it in a final product. You would still need a base board and that would make it more fragile. If I would just use an Arduino as a finalproduct, I would remove the connectors or buy a mini pro and solder screw terminals on it. Making it more rugged

  Are you sure? yes | no

Nice. It would be easier to get these on a back plane of some sort to have several work together.
