Replacement for Arduino Micro

Other Hardware 3rd Party Boards
1

Hi All,

I currently have a PCB that logs 9 analogue sensors (thermistors) and 8 digital (flowmeters) and transmits the data to a second Arduino using the TWI, I'm achieving this with an Arduino Micro that simply slots into the board.

I'd like to create my own PCB in it's entirety however I believe that BGA is out of the question. So that throws the 32u4 out the window. Can anyone advise on what Arduino compatible MCU I could use with enough analogue/digital inputs that could be hand soldered onto a PCB?

I'm looking at the ATMega 1280, but is that really possible to solder by hand, I may need to make up 25 of these!

Many thanks in advance, I'm looking forward to your suggestions!

@jamestech:
Judging from your software skills and current successful project, I would suspect that you are more than competent to make your own selection.

Perhaps the issue comes down to hand soldering? At qty 25, build a reflow oven... You will be glad you did.

I believe that BGA is out of the question. So that throws the 32u4 out the window.

Um. Why? 32u4 is available in several packages other than BGA (actually, I don't see it in BGA.) The TQFP has a large-ish pin pitch (0.8mm) that should be relatively easy to hand solder. (The 1280 in TQFP has a 0.5mm pitch, and more than twice as many pins, so the 32u4 would be MUCH easier than that.)
