Delptronics is an Austin, Texas-based maker of electronic musical instruments founded by Mickey Delp. The company designs and manufactures Eurorack synthesizer modules, analog drum machines, stompbox pedals, and DIY kits, with a focus on small-format, character-driven analog circuitry rather than sample-based sound generation.

The brand is best known for its "Little Drummer Boy" series of analog drum modules — the LDB-1, LDB-1e, and the later LDB-2e — which pack eight analog drum voices into a compact Eurorack module designed to evoke the sounds of classic 1980s drum machines such as the Roland TR-606 and TR-808. The LDB-2x expansion adds individual CV control over drum pitch and decay parameters. Other notable products include the Trigger Man gate sequencer, the Thunderclap analog handclap, the ThunderBell analog cowbell, the Theremorph optical-control synth voice, a CV-to-MIDI converter, and the WiiChuck module that interfaces a Nintendo Nunchuck controller with modular gear.

Delptronics operates as a small, builder-driven outfit serving the modular synth and DIY electronics community, selling assembled modules alongside solder-it-yourself kits. The company was recognized by the Austin Chronicle's "Best of Austin" awards for non-traditional musical instruments and is a regular presence at synth-focused industry events including NAMM, Knobcon, and Synthplex.

Delptronics has 2 products cataloged on Equipboard, including Tabletop Synthesizers and Modular Synthesizers. Their gear is featured by 2 artists, with the strongest followings in Electronic, Rock, and Jazz. Notable users include Merzbow and Richard Devine.
