The uBASE module is the size of a regular AE modular module and is the carrier (or BASE) for three micro modules of 1/3 size or two of 1/2 size. The uModules can be plugged in and removed easily, even with the AE system running, so you can reconfigure or add needed functions in form of micro modules "on the fly".
Included is a small "key" to lift also modules without knobs in an easy way.
You can find more information about this module (soon) on the AE Modular Wiki.
