🔍 Product Overview

The LOFREE Digit is a designer‑grade 20‑key mechanical numpad that moonlights as a standalone calculator — wrapping serious office utility in LOFREE's signature retro‑round "Sweet Bean" aesthetic.

Built around Gateron Blue clicky switches and PBT round keycaps, it delivers tactile satisfaction with audible response for high‑speed numeric entry. The dual‑personality firmware lets you toggle between Calculator Mode (onboard math engine, LCD‑style logic) and Keyboard Mode (standard numpad HID), with a killer trick: calculator results transmit directly to your active document via a single keystroke. With Bluetooth 5.0 + Micro‑USB wired, 3‑device pairing, monochrome LED backlight, and a 53‑hour runtime (backlight off) from its 800 mAh cell, it's equal parts functional tool and desktop statement piece.

✨ Key Features 🔢 Dual Identity — Calculator + Numpad

• Calculator Mode: Standalone arithmetic engine — functions without a computer.

• Keyboard Mode: Standard 20‑key numpad HID — NumLock‑aware, sends 0–9, ., +, −, ×, ÷, Enter, Esc, Tab, Backspace.

• Result Sync (The Killer Feature): In Calc mode, press = then Transmit Key — result auto‑types into your active Excel cell, Word doc, browser form, chat window, or note app. No copy‑paste needed.

• One‑Touch Toggle: Dedicated mode‑switch key — instant flip between calculator and numpad behavior.

⌨️ 20‑Key Mechanical — Gateron Blue

• Gateron Blue Switches: Clicky, tactile, ~50 g actuation, ~4 mm travel — crisp "clack" with each keypress.

• Full N‑Key Rollover: All 20 keys independently scanned — hammer away at high speed, zero ghosting.

• PBT Round Keycaps: LOFREE's iconic circular caps — dye‑sub legends resist shine/fade, pleasant fingertip feel.

• Standard Layout: 4×5 + 1 (Enter) grid — muscle memory transfers from full keyboard numpad.

⚙️ Technical Specifications
💡 Usage Tips

• Result Transmission: In Calculator mode, compute normally → press = → press Send/Transmit key (marked on board) → result types into your active app. Works in Excel, Google Sheets, Word, browser forms, chat, notes.

• Multi‑Device Flow: Pair to MacBook (FN+1), iPad (FN+2), work PC (FN+3) — one numpad for three desks.

• Excel Power Move: Calculator mode for quick mental math → send result straight into spreadsheet cell — no alt‑tab needed.

• Backlight Discipline: Keep backlight off for maximum 53 h runtime; enable only in dim cafés/night flights.

• Wired Priority: Plugging in Micro‑USB auto‑switches to wired mode — useful when BT is congested or during presentations.

• Pairing Reset: Hold FN + BT‑Pair for 3 sec to clear all paired devices and start fresh.

⚠️ Important Notes

• Micro‑USB (Not USB‑C): ❌ Uses older Micro‑USB port for charging/data — keep a cable handy or use adapter.

• No NumLock Indicator: Relies on host OS indicator — some laptops may need software NumLock toggle.

• Calculator ≠ Scientific: Basic four‑function + percent/tax only — no trig/log/engineering functions.

• Transmit Needs Focus: Result‑send works only when a text field/app has input focus — click target first.

• Gateron Blue = Loud: Clicky switches are audible — library/quiet office users may prefer silent switches (not available on this SKU).

• Backlight Is Mono: Single warm‑white color — no RGB cycling (design choice for retro aesthetic).
