Gateway Electronics

Established in 1960, Gateway Electronics is the go-to place for electronics enthusiasts, model railroad & train hobbyists, amateur radio operators (hams), robot builders, airplane fans, teachers, students, kit builders, prototypers, networkers, technicians and tekkies, geeks, gadget lovers, audiophiles, installers, service techs, sound pros, old folks, young folks, and pretty much anyone else who needs electronic parts!

Do we really have a store? YES! We're in St. Louis, MO -- we've got aisles of bins with little parts in them, shelves with old and new equipment, racks with wire and cable, and even a few geeky guys behind the counter to console you when you 'let the smoke out' of your project!

Our recent move to Chesterfield Mall means that we'll be sticking around for a while -- a brick and mortar store where you can see and touch the parts you want, bounce ideas off fellow shoppers, and exchange friendly banter with other electronics enthusiasts.
