 I sent these off for production at [OSH Park](https://oshpark.com/shared_projects/Js6JrEyC), and they arrived (in Singapore) a month later (Jan 17th -> Feb 17th). They turned out quite well, certainly no issues with the fab. I'll be using these for some nRF24 projects.
 
 After examining the PCBs, I can see a few things that could be improved in the design:
+
 * the font size I used for pin labelling is just barely large enough to read
 * I didn't allow space between the 2x4 pin header and the pin labels (with the pin adapter installed, the labels are partially obscured)
 * the board size does not match the nRF24 unit very well (the module overlaps the edge of the board). I think the module might be better rotated 90˚.
