I've added the 4.7 uF cap.
It also looks like I can remove all the 10 uF caps and change the VDDA cap from on 100 nF to one 10 nF cap and one 1 uF cap.
Removed 10uF caps on VDD pins. Changed VDDA caps.
Maybe add a small ferrite bead or low value resistor between VDD and VDDA to filter noise from CPU core?
Good call. I've opened an issue. https://github.com/PaxInstruments/labwiz-board/issues/48
The stm32f103 datasheet indicates Vdd3 needs a 4.7 uF cap.![screen shot 2016-08-18 at 00 01 23](https://cloud.githubusercontent.com/assets/281642/17743635/f6e7fb34-64d6-11e6-8a37-a02c9e54e286.png)
