Serpens Modular is a Eurorack synthesizer manufacturer based in Melbourne, Australia, designing and hand-building analog modules with an emphasis on accessible pricing. The company focuses on utility and modulation tools for modular synth systems, with an aesthetic that leans toward straightforward analog circuitry rather than digital or menu-driven designs.

Its catalog includes the Hydrus waveform mutator, which combines up to three CV or audio inputs through half-wave rectifier circuitry with per-channel attenuverters and DC offset; the Sirius four-pole analog low-pass filter with germanium diode distortion; the Antares dual analog modulator, an 8HP module with two LFO sources; the Ara sequential switch, sequencer and voltage source; and the Triple Attenuator for control voltage. The brand has built a small cult following within the Eurorack community, particularly through coverage on ModularGrid and Mod Wiggler.

Serpens Modular has 2 products cataloged on Equipboard, including Modular Synthesizers.
