Features

• Extended language support — one unified 6×9 font (Latin, Greek, Cyrillic) plus on-screen keyboard alphabets for Cyrillic, Greek, Polish, Czech, Slovak, German, French, Spanish, Portuguese and Nordic. Pick two in Settings › Keyboard (Main/Additional) and switch between them while typing

• Enabled sensor screens with support for onboard sensors (temperature, humidity, pressure, luminosity, CO₂) and GPS data

• GPS navigation — a full navigation suite that needs no extra hardware (details in the Tools Screen docs):

  • Waypoints — mark a spot (car, camp, water…) with a short label, see it on the trail map, and get live bearing + distance back to it; the list always offers a one-tap backtrack to where your trail started
  • GPS compass — heading derived from course-over-ground (no magnetometer needed), shown as a clear scrolling heading tape with a large degrees + cardinal readout
  • Navigate to anything — a saved waypoint, a node straight from Nearby Nodes, or a location someone shares with you in a message
  • Share & save locations — send a waypoint to a contact or channel; on the other end, navigate to or save any shared location with one menu
  • Live location sharing — broadcast your position over the mesh as you move (movement-gated, to a channel or contact) and see others who share theirs as pins on the map and live distance/bearing in Nearby
  • Locator — arm a geofence around a waypoint or a person, get alerted on arrive/leave or near/far, with an optional homing beeper that speeds up as you close in. Set from the Locator screen, Nearby Nodes, or Waypoints; target shown as a flag on the map
  • GPS trail — background route recording with an auto-fit map (waypoints + live position), summary stats, auto-pause on stops, and GPX export
  • Metric or imperial — one global Units setting drives every distance and speed across the UI

• Messages Screen — view and send messages, open message details, reply with quick messages or custom text, navigate to / save locations shared in a message, per-channel notification and melody overrides, add/edit/delete channels on-device

• Favourites Dial — pin up to six contacts for quick access from the home screen

• Settings Screen — configure display, sound, home page order, radio and system settings

• Clock Screen — view time and date plus up to three configurable data fields, with built-in clock tools (one-shot alarm, countdown timer, stopwatch)

• Screen Lock — lock the device to prevent accidental keypresses, with a lock screen showing time and sensor data

• Tools Screen — GPS trail & waypoints, compass, nearby nodes (with ping & navigate), ringtone editor, remote bot, auto-advert, live location sharing, locator, diagnostics, repeater, remote admin

• External Keyboard & Joystick — optional, auto-detected: CardKB for typing without the on-screen grid (Fn+Enter submits, Fn+letter picks an accent, Tab is Hold-Enter, Fn+Esc locks), plus a wired joystick for boards without one. Compact mode makes CardKB-only operation practical

• Auto pwr (Settings › Radio) — Adaptive Power Control: trims actual TX power on strong links (from ACK SNR) and ramps back up to the configured ceiling on weak/lost links; the home screen shows the live power

E-ink Display (Wio Tracker L1)

The e-ink variant targets the Wio Tracker L1 fitted with a 2.13″ GxEPD2 panel (250 × 122 px). Every screen is adapted for it:

• Adaptive layout — every screen reflows correctly in both landscape (250 × 122) and portrait (122 × 250) orientations
• Display rotation — configurable in Settings › Display; applied immediately and persisted across reboots
• Joystick rotation — independent of display rotation; useful for custom enclosures
• Full refresh interval — configurable in Settings › Display; reduces ghosting on long sessions
• Clock seconds suppressed by default — seconds are hidden to reduce per-second panel refreshes and extend display lifetime; re-enable in Settings › Display
