xQFP breakout board free PCB build

Posted on Tuesday, October 25th, 2011 in builds by DP

Matseng built a USB capable AVR MCU breakout board from a free xQFP PCB.

If you build a free PCB we’ll send you another one! Blog about it, post a picture on Flicker, whatever – we’ll send you a coupon code for the free PCB drawer.

    I freely admit that this is a butt-ugly build. But it does it’s jobs quite well. It’s nice to have all the basic necessities like usb connector, crystal, decoupling capacitors and 3.3 volt vreg already in place for a quick hack.

    Wow that is some creative soldering!

      Luckily the 0.8mm pitch of the breakout board was ok for the SMD USB connector and the header vias at 0.1″ pitch is perfect for soldering 0805 SMD parts between the pads.

      The 3.3 smd vreg was fitting just so-and-so.

      All the GND and VCC connections are at the back of the pcb with some additional decoupling caps.

    I really like the individual milled pin sockets. Where do you buy those?

    Same here. I think I still have a wire-wrap tool, but the wire itself has been dedicated to “white wire” corrections of late.
