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.

Whether you're upgrading a HHKB, Realforce, Leopold FC660C, or building a custom EC board, our collection offers options to enhance your typing experience with modern features like programmability, USB-C connectivity, and VIA/QMK support.
