VQFN SMD prototype adapter
2 for only $3!
I put these together to experiment with the new ATTiny microcontrollers from Microchip

I started with the VQFN24 package (0.5mm pitch) and brought them out to standard 0.1" pins (same size as a 24 pin wide DIP)
Since there was lots of room left on the board, I added additional mounting points for:
QFN20 (MLF20) 4mm x 4mm 0.5mm pitch(ATTiny 45, 85 and others)
VQFN20 3mm x 3mm 0.4mm pitch (newer 20 pin Xmega parts, and others)
8 pin and 14 pin SOIC
