Yes, just got one for my bike lights.

My !!/really exciting/!! Atmega 328p programming board.
It's got the 16MHz crystal and caps so I can program my chips to run at 8MHz off the internal clock before sticking them in my temp sensors (only have 1 so far though).

I've got a couple of 328ps but couldn't get them to work. Need to try again.

They're pretty easy to get working. Everything on that board will get it detected by AVRdude. You do need a USBasp to program it or upload a bootloader if it doesn't come with one.

But it should have have some caps and resistors and other bits to properly connect it all up.

I think I've got some of the correct caps and a ceramic resonator but couldn't get it working last time.
Still cheaper to buy an Arduino nano though!
Maybe it's cheaper to remove a load of the voltage regulator bits off a pro mini.

Really? Cheaper to buy a fully assembled board than a single chip? How much do you buy nanos for? My 10 Atmegas cost £20 so £2 each.
I did try disconnecting the voltage regulator and power LED from a mini but couldn't get the power consumption down far enough. Much easier with the DIP chips if you want to go low power.

I bought 5 Nanos for £9.57 early this year. £1.91 each.
I think if low power really is essential then the chip is the way to go.

Looks like you can get 10x nanos for ~£16 now.
Possibly even cheaper if you searched a bit harder -
