ErosTek ET312B: the reference point behind the modern 312 family

The ErosTek ET312B became one of the best-known digital e-stim boxes of its era. Its combination of dual-channel control, digital patterns, display-driven operation and link/audio features influenced a number of later projects.

Where it fits

Most relevant today as the historical benchmark for understanding later 312-inspired hardware.

Why the ET312B still matters

ErosTek states that the ET312B was developed in 1999 and remained in production for more than twenty years. That unusually long run helped make its controls, digital patterns and two-channel concept familiar reference points within the e-stim community.

Production ended, influence did not

Production was discontinued in 2021 as key components became increasingly difficult to obtain or obsolete. Later community projects and commercial implementations continued to reference 312-style concepts, but they are separate products and should not be presented as original ErosTek units.
