Replacement: None. We are no longer carrying this protoboard in our catalog. This page is for reference only.
This breakout board allows for standard surface mount, SMD and SMT, TQFP 44 pin packages with 25mil (0.8mm) spacing between pads. The PCB uses a double copper layer plated through-hole surface mount design. Square copper pads are located on the bottom side of the board for other surface mount components. Plated through-holes are off the center of square copper pads for creating soldering space. These work great with our protoboards.

Can I get a 32 pin 8mm version?!
I'd also like a 32 pin .8mm spacing version of this.
This board worked really well for prototyping with an ATxmega64D4
Would the DS3234 work on the SMD side of this board?
What about 48 pin?
I'd love to see more QFP adapters in general, particularly ones for the most common pin counts (32, 44, 64, 100). Of course, if I'd just get off my butt and learn Eagle, I could just have BatchPCB make me up a bunch of them... ;)
I'd like a 48 pin .5mm version
This is just the right size for Parallax's Propeller Chip (44-Pin QFP). I been able to attach both DIP EEPROM (using the extra prototyping holes) and SOIC EEPROM (using the square pads on the back side of the board). To match the pitch of SOIC chips, I cut the square pads on the back in half. I use a DMM to make sure I'm electrically isolated the half pads.
I've used these a lot and really like them.
