Hardware Description

Processing Platform​

FIBER is built on the Raspberry Pi Compute Module 4 (CM4), providing a reliable ARM-based processing platform with extensive Linux ecosystem support. This enables long-term maintenance, broad application compatibility, and flexibility in custom firmware development.

Key characteristics:

  • Quad-core Cortex-A72 (ARMv8, 64-bit) @ 1.8 GHz
  • Memory options: 1/2/4/8 GB RAM, and 8/16/32 GB eMMC storage
  • Industrial temperature options
  • Compatible with upstream Linux packages and standard development workflows

Sensor Interfaces​

1-Wire Inputs​

  • Eight fully isolated, independent 1-Wire ports
  • Designed for digital temperature probes and similar 1-Wire sensors
  • Per-channel LEDs indicate input activity and sensor status

868 MHz ISM Radio​

  • Integrated long-range ISM radio (LoRa-capable) for communication with wireless sensors
  • Compatibility with HARDWARIO STICKER sensor nodes (temperature, humidity, motion, etc.)
  • Suitable for distributed sensing across buildings or facilities

Display & Local Interaction​

  • Backlit graphic LCD
  • Physical buttons for basic navigation and device control
  • Suitable for viewing instantaneous sensor values, system states, or diagnostics

Acoustic & Visual Signaling​

  • Piezo buzzer for alerts or diagnostic feedback
  • Status LEDs for each 1-Wire input, providing immediate hardware-level insight

Power System​

  • Supports Power-over-Ethernet (PoE)
  • Integrated 3.6 V Li-Ion backup battery
  • Ensures stable operation during power interruptions

Connectivity​

FIBER provides multiple communication interfaces suitable for a wide range of installations:

  • Ethernet (LAN) Reliable wired networking for industrial environments.

  • WiFi For wireless deployments without physical cabling.

  • Bluetooth Low Energy (BLE) Useful for commissioning, diagnostics, or peripheral connectivity.

  • LTE (optional) LTE Cat 4 module available for remote or mobile deployments.

  • 868 MHz ISM Radio Enables communication with remote STICKER-based wireless sensors.

These interfaces allow FIBER to integrate into both existing industrial networks and modern distributed IoT architectures.

User Interface​

FIBER offers several local interfaces designed for clarity and quick diagnostics:

LCD Display​

  • Backlit graphical display
  • Shows real-time sensor values and device diagnostics

Buttons​

  • Navigation and confirmation controls
  • Suitable for on-site interactions without external tools

Status LEDs​

  • One LED per 1-Wire port
  • Visual feedback for sensor presence, activity, and errors

Acoustic Buzzer​

  • Provides audible alerts
  • Useful for alarms or feedback during configuration
