- Tue Oct 14, 2014 8:05 am #1614 @Claude I cant do it without a via (2 layer board) and also a 15 mil track is impossible to connect to the QFN

Though I'll be using multiple (parallel) vias in the VCC track.

The PCB is based on a SOB PCB design by dangerousprototypes ( http://dangerousprototypes.com/docs/Sick_of_Beige ) only it is 1200x1200 mil (almost 3x3cm). Thickness will be 0.8mm. I'm still not totally happy with the layout as it is too crowded in one corner, but prolly ok for a first go.

Comments are welcome and prolly give some of the remaining boards away (if usable that is )

Also, it looks like you have ground plane on the bottom of the board under the antenna. I'm not an antenna expert, but I thought the board was supposed to be free from anything above and below.

I wanted to keep the ground near the feedline on both sides, and this seems to be a way

missed that one! it was already getting midnight and my eyes were almost shut.

Thanks for reviewing
