Not that I know. Antonio Villena may know something about it.
What you could do is to take the wifi board and the MIDI board, without pinheaders soldered, and use a larger pin header to make your own stacking, soldering one module first, and the other one just above it, leaving a clearance of, say, 2mm between boards.

Ah, thanks Mcleod. Yes, my board and the VGA/Wifi connector came from Antonio.

(I had some account problems but Hark0 has sorted me out now).

Your suggestion about using a double-ended pin header kind of thing makes sense, I have done something like this before with a 'HAT' for a Raspberry Pi, I may even still have some usable single-row pins somewhere...

I've put the images in URL links to prevent spamming the forum, but I think you know exactly what I've got so probably no need :-)

Hmmm... sounds like a future project for steady hands, or a niche market for someone who already had the ability... ;)

Nice to know that in theory its feasible, Ill have to think about it before I attempt anything risky... Might just chicken out and spend on a 2nd Uno instead though... ;)

Ha ha, the thought of just buying another one immediately crossed my mind too...
