esp-buttA physical controller for intimate devices

No phone. No app. Just knobs, sliders, and hundreds of compatible toys.

No phone required

A standalone physical controller — power it on, pick a device from the OLED menu, and you're in control. No app, no pairing ceremony.

Built on Buttplug.io, the open intimacy device protocol. If your toy speaks BLE and Buttplug knows it, this controller can drive it.

Two analog sliders and a rotary encoder with push-click give precise, tactile control over intensity — no touchscreen fumbling.

KiCad schematics, 3D-printable case, and Rust firmware — everything needed to build, modify, or extend your own unit.
