using switching regulator board on flipped-over IsoPod

[larryat]

I'm using the flip-the-IsoPod-and-plug-in-all-connectors-to-another-board method for connecting the IsoPod since otherwise there would be too many ribbon cables!

What is the clearance for this when using the switching regulator (SR) (which mounts on the headers' side of the board)?

Is it possible to mount the SR sub-board on the side where the regulators currently are?

The height of the SR board is allitle higher than the header pins. SR height is approx. 0.5" and the bottom of the IsoPod V2 is approx. 0.05"

Yes, but there are also caps (C3,C4) and cystal, and reset IC on the top side which you need to taking care of too.

I guess, The best option for your mounting application is using the V2 with SR adaptor board on the top side with the headers install on the bottom side of the IsoPod V2

You can also use V1 with SR and J2 & J3 must install on top side. Becasue J2 & J3 of IsoPod V1 is not on grids with the prototype board.

I'm not sure I completely understand your answer.

OK -- a little higher --- how much is a little? I measure the tops of the current header pins as 0.420" from the back-side of the PC. Does the highest point of the SR daughter board only project 0.080" above the pins? (That would be pretty much OK.)

I'm avoiding the 3 caps and the crystal. The reset IC is also avoidable after being carefully tipped over (otherwise, it hits the mating PC board).

Is it an option to install all the headers on a V2 board upside down? Sounds like an additional expense for y'all (to be passed on to the customer!). Do you do your own header installation, or are the boards kitted-out?

Also, (I haven't looked about yet) perhaps there are really tall female headers which would increase the standoff between the two boards?

Yes -- I was very pleased that the pins line up all on 0.1" centers on the V2 board. (Should I also mention, rather irked when I noticed that they don't on the V1 board!)
