AVR mini board with additional boards

Picture of AVR mini board with additional boards
Somewhat similar to PIC 12f675 mini protoboard, but extended and with additional boards.
Using attiny2313.

Step 1: Scheme

Let us first start with a scheme. The scheme is pretty obvious since it only connects attiny2313 with the pins and the only additional elements are resistors and capacitor for reseting the microcontroller.

Step 2: Bottom view of the board

Here is the bottom view of the board, so you can see the main idea with this kind of boards.

Step 3: Now what?

Picture of Now what?
Here are some ideas to extend the boards with "extension boards".
Let me start with power supply. If you are using 9V battery you can make this kind of board with 78L05.

Step 4: Another idea

Picture of Another idea
I've also created a board with 4 LEDs and two buttons. The elements can be connected to any pin using wire with one female and one male side.

Step 5: The end result

Picture of The end result
What wanted to get is flexibility with the boards so I can inter-connect them as I like.
For example like that.

Step 6: And the top view

Picture of And the top view
Just to see how the whole thing looks from the top.

Step 7: Conclusion

We have come to the end of this instructables.
I've showed you the idea, how to create a flexible board which can also be attached to the protobard.

The SILs are used for wire-wrap tehnique, but I used them to get connection between the boards.

Better than Arduino. Each function is separated (power, IC, HID, etc..) I'm looking forward to when you're offering these for purchase. :) Yeah, easy to make, but why not support someone with a great idea?

This is like a mini arduino with sheilds! awsome.

where do you get your parts from and can i get the part numbers ive been having trouble finding those kind of headers
Digikey part A209-ND is a close match, and will allow stacking. The socket isn't as deep, but will accept its own pins. The catalog page. (I can't post the datasheet for the actual part because the URL has an embedded space that the Instructables link tool won't parse correctly).

I have found that Digikey often charges outrageous prices for the things that I can get from other sources.  Jameco has the WW sockets/headers for about half of what Digikey wants.  They have 20-pin and 30-pin SIPs rather than the 25-pin that Digikey has - the 20-pin is just under half price and the 30-pin is just over half the Digikey price.

Jameco part numbers:
101283 - 20-pin WW2 single row
104054 - 30-pin WW2 single row

Check out Jameco's catalog page at: www.jameco.com/Jameco/catalogs/c102/P83.pdf - the part numbers are links to the description page which has the datasheets and pricing ($1.95 and $2.95 today as opposed to Digikey's $5.42 - even in Qty of 500, Digikey is higher than Jameco's single qty price)
cool thanks

I am not sure for the US, but in Europe you can find them in Conrad.

i usually order off digikey it the only place that let you get small orders and has prices in Canadian $. thank for the response but the page was in German, and probably cost alot for shipping.

What do you buy for this? (I'm not a technogenius.)
not the bafftub!!!!!!!!!!!!!!.bmp
That is hopless. All you can do with that is lots of love.
This is like arduino shields for the attiny2313! Can you post the designs for the PCBs?
iknowirule35 years ago
Actually where do you buy the connectors in US?

i need a little more understanding on where to put the capacitors and resistors to prevent switching noises or whatever it makes when being programmed.
I love it. Takes the advantages of both of the carrier types that I've made and then goes modular/stackable. And you still have all of the pins directly accessible from the top. Hotness!
b0j3 (author) 7 years ago
Anything you want. I'm using it to decode dcf77 receiver (atomic clock) and since I needed accurate time I've made another board with quartz and two capacitors. But since it's microcotroller - you can program it to do whatever you want.

what does it do exactly?

You should create some boards with motors and wheels then some sensors and you'd have a nice little robotics platform.
b0j3 (author)  25Kilovolt7 years ago
This is my intention.
25Kilovolt7 years ago
this reminds me of some robots i saw on discovery channel a while ago. They were form some American university like MIT of some thing. they had piggy backing boards with functions like wheels, treads, micro controller, battery, and many different sensor boards. i really like the modular idea to it.
For more on the stacking concept, check out the PC/104 standard used in many industrial and embedded designs. It's an ISA slot (yes, old 16-bit!) implemented on stackable pins like this, with a physical standard that defines how big the boards can be and where their mounting holes are.
Awesome! I could see a modular-type electronics toy based on this in the future. Nice job!
Very nice! I like the stackable concept.

You should add info about the ISP cable for your main board--a DAPA cable. Another instructable with the cable/programming info is here:

Yeah, I totaly forgot ISP pins. Thanks for the comment and link.

Internet service provider pins? Woot haxxoring isps!

Oh yes. ISP can also stand for In System Programming, hm ...

oooops. Didn't really intend to post this comment as reply to Muffinator....
Hehe, you can delete your comment and re-post, if you want =)
Yeah, but I think it'll mess the thread up too much now ;)

Awesome i already built the avr ghetto programmer and now I am making a serial programmer. Instructables like this are great for getting started with micro controller programing.
Dzwiedziu7 years ago
Very good idea. If you have an separate programming board, a "module" won't be neccesary. But making one will make things simpler.
Sgt.Waffles7 years ago
I have no idea what that is/does, but the instructable is well put together.
