FIBER Lite

FIBER Lite is a compact, all-in-one appliance built on the Raspberry Pi 5 for quickly bringing up and testing LoRaWAN devices — in particular HARDWARIO STICKER and HARDWARIO CHESTER — without needing to stand up a separate LoRaWAN network server, database, and visualization stack for every bench test.

Unlike the industrial FIBER (built on the Compute Module 4, with an integrated LCD, 1-Wire sensor hub, and buzzer — see FIBER), FIBER Lite is a pure software appliance: a Raspberry Pi 5, a LoRaWAN concentrator card, and a DIN-rail enclosure, running the complete LoRaWAN data pipeline out of the box.

Data Flow

LoRaWAN device (STICKER, CHESTER)
        │  RF
        ▼
RAK5146 concentrator (RAK2287 Pi HAT, SPI)
        │
        ▼
ChirpStack v4  (LoRaWAN Network Server)
        │  MQTT (uplink/downlink)
        ▼
Node-RED  (payload decoding, routing)
        │  write
        ▼
InfluxDB  (time-series database)
        │  query
        ▼
Grafana  (visualization, dashboards)

A landing page on port 80 links to every service and shows live system stats (CPU, memory, disk, temperature, uptime), so the device is usable without memorizing ports or IP-to-service mappings.

Bill of Materials

Component	Notes
Raspberry Pi 5	Main compute unit
RAK WisLink RAK5146	LoRaWAN concentrator card (SX1302), SPI
RAK2287 Pi HAT	SPI adapter for RAK5146 → Raspberry Pi 5 GPIO header
DIN-rail enclosure	For cabinet/rack mounting
microSD card, 32 GB, high-endurance	OS + logs + time-series database (write-heavy workload)
Standoffs	Mechanical mounting

Key Features

Feature	Description
Raspberry Pi 5 platform	Standard Raspberry Pi OS, full root Linux access.
Built-in real-time clock	Pi 5 has a native RTC — no external RTC chip/battery needed.
Complete LoRaWAN stack	ChirpStack v4, Node-RED, InfluxDB 2.x, and Grafana pre-integrated.
Branded landing page	Single entry point with service links, live system stats, and an SSH quick-copy.
LAN or Wi-Fi	DHCP on Ethernet, Wi-Fi as fallback.
USB-C powered	No PoE injector required.

Typical Use Cases

• Bench-testing new STICKER or CHESTER firmware builds before field deployment
• Quick LoRaWAN network demonstrations without cloud dependencies
• A portable, self-contained ChirpStack instance for training or workshops
