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
