 Bigger Bigger  Smaller Smaller  Reset Reset

I have started developing a temperature controller for my fridge (the why is a long story) and when I got to the stage of designing a stripboard shield to hold the various extra bits (leds, resistors, transistors, 5v power supply etc) I suddenly realized that it requires very little extra effort to put a standalone 8Mhz 328 chip (I already have one) on the stripboard and header pins for an FTDI cable (I already have one) so there is no need for the Uno board at all.

I was also reading this other topic http://forum.arduino.cc/index.php?topic=179754.0 and this Chipkit product http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,892,1174&Prod=CHIPKIT-DP32 caught my eye. I wonder is there an equivalent for an Atmega328?

I have seen various references in various Topics on this forum to PCBs that are available for building Arduino clones but I can't remember them now and I haven't been able to find a list of them anywhere so that I can compare them. Also I don't actually recall seeing one that has space for additional parts.

I have no interest in designing and making a custom PCB - it makes no sense for a one-off project and I will be quite happy using stripboard unless there is a convenient alternative.

Thanks for those links, but they aren't quite what I have in mind.

The Evilmadscientist product is too small and hasn't enough space for building a complete project and the other two are just as expensive as an Uno.

Putting a Mega328 onto stripboard is easy, the tricky part is all the other components.

IMHO those boards offer very little advantage (apart from having the Mega328 pinout printed on them).

Sometimes, you can get a bit aggressive with the ”PU" DIPs:

Not a pretty pig, but functional and inexpensive for one-off projects.

Ummmm..... Agreed.
My suspicions are that many hobbyist-enthusiast simply gravitate to labeling as the Arduino physical/logical mapping is an uncomfortable topic.  Worst, it is often inconsistent!

Ummmm... a 30-cent sticker for a $2.00 chip seems a bit excessive.  Do people really do this?  Rhetorical question!  OF course they do or the labels would not be advertised.

And... I've seen others on the web without the logo and with wrap-down skirts and so on...  Just buy a roll of double-stick tape and have at it.

Yes, free is nice:

I use strip boards for projects like that, here is an example:

I've also used the EvilMadScientist board for projects where I only need a few extra parts. Saves a bit of mucking around.

Here's an approach I took for a circuit that I use occasionally but did not want to dedicate the various modules to, so I soldered female headers to the protoboard.

The microcontroller is an AFI DC Boarduino; a Pro Mini would work nicely as well. With its built-in 5V supply, the Boarduino relieved me from the task of having to wire up a power supply on the protoboard.

Hi Nick,

I haven't come across the sort of stripboard you have used - it's probably what I'm looking for. It looks easier to use than Veroboard. Is there a brandname or a UK supplier?

Your project looks very neat - but why not use your phone???? smiley   smiley

PCBs that have the same connections as a breadboard?

Search for "breadboard pcb" on eBay.

This is what it looks like:



I don't know any more than that, except I probably bought it from Jaycar in Australia.

I don't think I have seen a single "alarm" app that sounds Monday to Friday but not on Saturday/Sunday. Surely millions of people must want that?
