ElfKey

ElfKey is the mobile companion app for PCsensor hardware. SUPPORTED DEVICES - Foot switches: FS series - Macro keypads: MK series, BTC24K - Multifunctional keypad: Delta21 TWO WAYS TO USE - For foot switches and macro keypads, ElfKey is an on-the-go configurator: connect over Bluetooth to reassign what each key outputs. Settings are stored on the device, which then works standalone via USB, Bluetooth or a 2.4G receiver depending on the model — no phone involvement at runtime. - For the Delta21, ElfKey is a live remote: your phone connects to the device over Bluetooth, the device connects to your computer over USB as a standard keyboard/mouse, and in-app actions are relayed to the computer in real time. KEY FEATURES ◆ Bluetooth Connection - Scan and connect your PCsensor device with live connection status and auto-reconnect ◆ Key Mapping (foot switches / macro keypads) - Assign any key as keyboard keys, strings, mouse actions, media commands or macros - Multi-layer key profiles: add, delete and switch layers on the fly - Advanced triggers: double trigger (press/release), loop trigger, page-turning mode - Output modes: single, continuous and repeat, with adjustable count and speed - Refresh a single key or reset the whole device ◆ Delta21 Live Control - Virtual keyboard with up to 6 simultaneous keys for easy shortcut input - Touchpad to move, click and scroll the cursor on your computer - Combined keyboard + touchpad control - Media controls: volume, playback, browser and system shortcuts (Windows / macOS) - App shortcut panels for PowerPoint, Word, Excel, Photoshop, VS Code and Chrome — one tap to trigger - Text Notes: save frequently used text and type it into your computer through the device; protect notes with a PIN ◆ More - Simplified Chinese / English interface PLEASE NOTE - ElfKey works together with PCsensor hardware. Without a device you can browse the interface and manage Text Notes, but key configuration and computer control require a physical device. - No sign-up or login required. We do not collect personal data. Bluetooth permission is used solely to connect your own PCsensor device. - Connection methods and features vary by model — please refer to the product manual.
