HARDWARE ARCHITECTURE

ENGINEERED FOR SURVIVAL. ZERO BLOATWARE. PURE UTILITY.

01 / POWER PATH MANAGEMENT

  • Dual-Source: 1.5V AA primary with seamless 3.7V Li-ion fallback.
  • Extreme IQ: TPS61099 boost converter, sleep current < 10μA.
  • Endurance: Duty-cycled polling yields 30-90 days on one AA.

02 / DISPLAY & HAPTICS

  • Zero-Power: MIP/E-ink panel, ~0μA draw during static display.
  • All-Weather UI: 6 fully-sealed tact switches for T9 macro input.
  • Alerts: High-penetration ERM motor & dual-color status LED.

03 / TELEMETRY & NETWORK

  • Cellular IoT: LTE Cat.1 / NB-IoT module utilizing PSM/eDRX.
  • Pure Payload: MQTT protocol, minimizing HTTP overhead.
  • SOS GNSS: Cold-start positioning hardware, strictly off until override.

04 / CRYPTOGRAPHY & PRIVACY

  • Hardware E2EE: AES-GCM / ChaCha20 encryption decrypted locally.
  • Zero-Knowledge Relay: UUID-based ciphertext routing, no logging.
  • Physical Whitelist: NFC/IR proximity key exchange to block spam.
