Prototyping shield is designed for use with the WeMos D1 mini
and mini Pro development boards. It allows you to
create your own custom WeMos shield which can then be plugged directly
into the WeMos mini. Supplied with the PCB are 3 sets of headers
(requires soldering) which also allow for multiple shields to be stacked
on top of each other. The PCB gives full access to all the WeMos D1
mini interface pins including power.
