Compact Split Module
The Compact Split Module makes it possible to use two top modules or create more compact designs. Now you can create much more devices that combine for example LCD Module, Climate Module, PIR Module and many others. You can also use this module to create two stacks of modules and create more compact devices.
This module has bottom entry pins which makes the module thinner. This module cannot be connected directly to the Battery Module because of collision with Battery Module's tag connector.
Please see also Split Module which is a bit thicker, but doesn't collide with Battery Module.
