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 (https://www.mikroe.com/click/sensors) 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?
