UEXT Shield for OLIMEXINO-STM32F3

[rosmo]

I'm thinking of using OLIMEXINO-STM32F3 in a project, but I would need two UEXT devices.

In my case a rs485 and a Env sensor. It would be nice to use Mikrobus click devices too.

I did a quick draft but my PCB skills are amateur: http://bit.ly/45WCPPN

Would you consider turning that into a 'proper' board?
