We find capillary wave turbulence (WT) to span multiple dynamical regimes and geometries -- from weakly to strongly nonlinear WT (SWT) and from shallow to deep domains -- all within a 40uL volume millifluidic system. This study is made viable with recent advances in ultra-high-speed digital holographic microscopy, providing 10-us time and 10-nm spatial resolutions for images across the entire field of view, and encompassing a complete wave system at speeds sufficient to capture the salient wave phenomena. We provide a set of tractable parameters that identify the four fundamental WT regimes present in this simple system. A proposed nonlinearity measure permits comparative analysis while varying input conditions. This work augments current understanding of WT regimes and behaviors, and directly applies to many fields beyond fluid mechanics. For example, SWT appears upon the fluid interface at powers less than required for atomization, indicating that further study of SWT is needed to properly understand ultrasound-driven fuel spray atomization and drug and agricultural nebulization.
