Anyone have an extra Atmega168 qtfp?
Mouser seems to be back ordered til march... hot smiley
Or at least know of a supplier that might have it in, I want to get it this week... hopefully.
Thanks

[search.digikey.com]

I go to DigiKey first before any others, as they have more than anybody else IMO

Also, try Jameco

I tried digikey already, but I didn't think about Jameco, thanks.

Mouser doesn't have the 20mHz until March, the 10mHz they have in stock.
Digikey won't have any until Jan.
Jameco seems to have the right one in stock but won't ship for 8 weeks.

I guess I'll have to wait until Jan... and I was hoping to have a minimug by this weekend or at least years end. such is life....

I'll double check Jameco because there seems to be some discrepancy in availability.

[www.moderndevice.com] seem to have the 168 and 328 in stock for $4.30 and $4.50. I'd buy the ATMEGA328P. It has twice the ram and twice the flash memory and is the "new" arduino for $0.20 more.

[www.adafruit.com] seems to have them in stock too....$6.00 though!

would the 328p be compatible with the new extruder controller?
If so, thank you this helps me no be at a standstill.

In the arduino software you have to select which chip you are using but it's invisible to the user other than that.

it appears that moderndevice and adafruit only have the through hole not the qtfp,
It seems that none of the listed sites have qtfp atmega chips with the same or better specs. damn I didn't think it'd be this hard to find a chip. lol

OMG, I finally found a place. I am apparently a little lysdexic and kept typing qtfp instead of tqfp. Here is a link to a place that has them at a good price too.
[www.taydaelectronics.com]

$1.90 each, nice, I got 3 just so I'd have some for my next build (assuming gen 3 electronics are still used. One thing that was odd, standard shipping for 0.99 express for $35
Anyway, let's see how it works...

Looks like the Atmega8-16AU has half the storage space as the recommended Atmega168-20AU. Will 8kb be enough?

JeremyRuhland: as far as I know, fitting everything into 16k is enough of a squeeze as it is, I think you'll get nowhere with an 8kb part unless you rewrite everything in fiercely optimized assembler
