WEMOS D1 Mini Dual Base - takes 2 Stacks of D1 Mini Modules

The D1 Mini Dual Base takes 2 stacks of Wemos D1 Mini compatible shield and modules. These Base is in technically terms a "back plane", and it connects the pins with the same names and functions between the 2 stacks.

The use of such a Base makes it much easier to build larger projects, than stacking everything piggyback on top of each other.

The Dual-Base comes with the necessary 4 connectors for D1 Mini compatible modules and shields
