Product Overview

Overview

The Ledger Flex™ sits in the "touch confirmation + full connectivity" sweet spot: its E Ink touchscreen presents key information clearly, and it brings together Bluetooth BLE, USB-C, and NFC — handy for switching between phone and desktop workflows.

Connectivity & Compatibility

  • Mobile: Bluetooth BLE 5.2 (iOS and Android).

  • Desktop: USB-C.

  • NFC: used for Recovery Key / Security Key scenarios (per official documentation).

System requirements follow the official checklist: 64-bit Windows, macOS, or Ubuntu on desktop, and iOS 14+ / Android 10+ on mobile. Chromebook is not supported.

Display & Interaction

The E Ink touchscreen offers 16 grayscale levels at 480×600 resolution — engineered for a "read carefully, then tap to confirm" workflow.

Size & Weight

Approximately 78.4 × 56.5 × 7.7 mm, weighing about 57.5 g — a balance of readability and portability.

Security Reminders

  • Setup and recovery information must be generated and kept offline, by you alone.

  • For every approval or signing action, cross-check what the device screen shows.

  • Treat unfamiliar links, unknown installers, or "confirm now" pressure as red flags — slow down and verify.
