EC PCBs to upgrade your Topre experience
Discover our premium selection of Electro-Capacitive (EC) PCBs, designed specifically for Topre-compatible keyboards. Unlike traditional MX mechanical switches, EC technology offers a unique typing experience beloved by enthusiasts for its smooth, tactile feel and distinctive sound signature.
Our EC PCBs are perfect for keyboard modders looking to breathe new life into stock Topre boards or build custom EC keyboards from the ground up. Each PCB variant is engineered for exceptional performance, reliability, and compatibility with popular Topre-style keyboards.
