... because this information is scattered everywhere and not complete.
And o word about the heights
Ok, the Buffalo is 2x3.3 inches, but the IvyIII...? 3.3x3.3?
Customers like me, waiting 6 weeks for an order
could use this time waiting to prepare the housings.
In my case, I do not find reliable information on the height oft the stacked BuffaloII and IVY with mounted stock parts.
I want to put them into an Aluminum Die Casting box, so I need to know, if 35mm (1.3inches) are sufficient.
All the best,

Don't know exactly but standoffs are 0,5", interboard standoffs 0,65", board thickness is probably the standard 0,0625". Then there is the height of the components on the DAC (and the mounted AVCC module). Adding up all the known heights gives 1,28" in height without the components and AVCC module on top of the buffalo.

So there's no chance you can get it in an 1,4" case, even with smaller standoffs and different mounting of the AVCC module.

By the way, this info you could have easily deducted yourself .

Let me know if you need to know the exact height of the IVY+Buffalo+AVCC with normal standoffs and mounting, I could put a ruler next to it.

Height is slightly above 46mm including AVCC. I can't measure it exactly anymore because everything is already mounted in the testing enclosure.

Received the boards last week, so time to measure:


The overall height of the stacked IVY+Buffalo Combo is 44 mm, when Ivy is the bottom part.
The base standoffs are 12mm, the interboard standoffs are 16mm.
One can easily lower the overall height of the IVYIII / BuffaloII combo to 34mm by:

-Using 5mm base standoffs
-Omitting the plugs of the connectors for the current output, using only the rails.

The tallest parts on the IvyIII are the voltage connector and the electrolytic caps, they are about 12mm.
The voltage connector can be ommitted and the cables from the power supply can be soldered directly to the Ivy/Buff
There are SMD parts on the bottom of the Buffalo II,
but not in the area where the electrolytic caps of the IVY are.

With this mod, 13mm standoffs can be used. (i.e.12mm extended with a spacer/washer)

I have not tested the original height of the AVCC Module, but lowered it as well.
So after the mod there will be 1mm air betwen the Ivy´s caps and the bottom of the Buffalo.
Without the connectors plugs, the connections between Ivy and Buffalo have to be soldered.

The Placid BP has an overall height of 52mm with heatsinks and standoffs.
I guess, it is the same with the Placid.

Without the standoffs and heatsinks, it is 28mm
The electrolytic caps are the tallest partson the Placid, 26mm.
With different heatsinking (for example mounting the power transistors directly on the enclosure),
the height can be reduced to 40mm.
Probably 35 mm with 5mm standoffs and much care taken not to produce shorts

Buffalo II has 50.5mm x 84mm, about 14 mm height including the smd parts at the bottom
Ivy III has 50.5 x 110.5mm, height is about 15mm including solder joints at the bottom.
The screw-fitted connectors take a bit more height the bottom but can be shortened.
The Pacid BP has 89 x 76mm, 42 mm height with heatsinks, including the solder jointes of the heatsinks at the bottom.


BTW, to me, the built quality of the boards is superb. Verx thick copper, I have to heat my 1mm solder tip to 400 degrees celsius when soldering parts connected to the ground.
