Topic: New version or old version boards for Arduino starter? (Read 916 times) previous topic - next topic

It seems that there are different versions of Arduino boards.
For a starter, should I get the newer version or the old version?

Obviously, the newer versions.  That's why versions exist.  The older versions have bugs and mistakes.

I have an original UNO that hasn't given me any trouble yet.

Buy the currently available board, but there is no fundamental problems with using older Arduino boards.

which have never been fixed (cough header spacing cough)

I still use my Duemilanove, purchased in late 2010, for occasional testing.

With older cards, you may see occasional hangs after a reset.

If you're seeing the difference between the Unos that have a flat, square, SMD chip and the ones that have the big, rectangular, replaceable DIP chip then you would want the one with the big DIP chip. Because it's replaceable, obviously, or really easy to use to program additional, ~$3 chips that you can use in standalone projects.

I see a difference in getting around auto-reset when using Arduino as ISP and funny enough, the Duemilanove isn't supposed to need any of those.

Also to program blank 328's you can't just pop them into an UNO socket and go. They need a bootloader loaded which you can do using an ISP. I've done it using my old UNO, a breadboard and a few jumpers and cheap components... but only using IDE 0023. Yeah. I am soooo out of date! And yet, my sketches work once I get the program bugs out.

I get Mega328P-PU AVR's for about $2.50 ea in small quantities. At 10+ they get even cheaper.

Older chips such as Duemillanove has a problem with 3.3v supply. It's not a separate regulator but brought out from the FTDI chip. If you accidentally put too much stress on it, the FTDI chip will be ruined. Gotta student/beginner proof it like this (i.e. plug up that 3.3v pin):



Yeah I still have my Duemillanove from 2009 but the DIP socket has shown some sign of oxidation. I'm just using it to load firmware to ATMEGA328P so I removed the chip and added a ZIF socket.
