Description

The RAKwireless Blues.ONE is a professional-grade LoRaWAN node platform built on the WisBlock modular ecosystem. Its core is the RAK4631 module, which pairs a powerful Nordic Semiconductor nRF52840 microcontroller—capable of running complex firmware on Arduino, Zephyr, or CircuitPython—with a Semtech SX1262 LoRa transceiver optimized for sub-GHz operation. This combination provides the processing muscle and ultra-low-power, long-range wireless link essential for remote sensor networks.

Designed for system integrators and developers, the board’s architecture emphasizes flexibility and rapid prototyping. The included RAK19007 WisBlock Base Board exposes four sensor module slots and one IO slot, allowing for the quick assembly of custom monitoring solutions without soldering. Power options are equally versatile, supporting direct USB-C programming, integrated Li-Po battery charging, and harvestable solar input, making it ideal for field deployments in smart agriculture, environmental monitoring, and industrial telemetry.

Key Features

  • Modular Sensor Integration: Four WisBlock sensor slots enable plug-and-play connection of temperature, humidity, motion, and other environmental sensors for rapid IoT prototyping.
  • Long-Range LPWAN Connectivity: Semtech SX1262 LoRa transceiver delivers industry-leading link budget and sensitivity for reliable data transmission over several kilometers in rural areas.
  • Bluetooth 5.0 for Configuration: Integrated BLE via the nRF52840 allows for easy device setup, firmware updates, and local data readout using a smartphone or gateway.
  • Expandable Cellular Backhaul: Interface with the RAK13102 WisBlock IO module to host a Blues Wireless NoteCard, adding global LTE-M/NB-IoT/GSM connectivity for hybrid network solutions.
  • Sustainable Power Design: Onboard battery management and MPPT-enabled solar input (up to 5V) support perpetual operation in off-grid and solar-powered applications.
  • Developer-Friendly Ecosystem: Fully supported by the Arduino IDE, PlatformIO, and Zephyr RTOS, with extensive libraries and examples provided by RAKwireless.

Applications

  • Smart Agriculture & Environmental Monitoring: Deploy for soil moisture, temperature, and humidity sensing across large farms with data sent via LoRaWAN to a central gateway.
  • Industrial IoT & Asset Tracking: Monitor equipment status, track high-value assets in warehouses or yards, and transmit telemetry over private or public LoRa networks.
  • Smart City Infrastructure: Implement in waste management sensors, parking space monitors, or streetlight control systems requiring long-range, low-power wireless links.
  • Hybrid Network Gateways: Use as a programmable edge node that can bridge local sensor data via LoRa and backhaul it through an optional cellular module for remote server connectivity.

Frequently Asked Questions

How do I program the RAK Blues.ONE module and what development frameworks are supported?

The module is programmed via the USB Type-C port using the Arduino IDE with the RAKwireless Arduino BSP installed, or through PlatformIO. It is based on the Nordic Semiconductor nRF52840 chip, which is also supported by the Zephyr RTOS and CircuitPython for more advanced firmware development. You must select the correct board definition (RAK4631) in your IDE to access the full GPIO and wireless features.

What is the power consumption in active and sleep modes, and how do I connect a battery?

The nRF52840 and SX1262 are both designed for ultra-low-power operation. In deep sleep mode, current draw can be as low as a few microamps. Active LoRa transmission current depends on output power but is typically under 120mA. Connect a 3.7V Li-Po battery to the dedicated JST battery connector on the RAK19007 base board. The onboard charger manages charging via USB or the solar input, which accepts up to 5V.

Can I use this module with cellular networks, and what additional hardware is required?

Yes, cellular connectivity is added via the WisBlock IO slot. You need the RAK13102 WisBlock IO module, which hosts a Blues Wireless Notecard (NBGL-500 for NB-IoT/LTE-M or SWARM for satellite). This Notecard plugs into the M.2 connector on the IO module, allowing the Blues.ONE to act as a hybrid LoRaWAN and cellular gateway or node, sending data to the cloud via cellular when out of LoRa range.

How do I configure the LoRaWAN region and parameters for my specific country?

The hardware is pre-configured for the 800MHz frequency plan covering EU868, RU864, and IN865. Region-specific LoRaWAN parameters (channels, data rates) are set in your device firmware. Using libraries like Mbed LoRaWANStack or the Arduino LMIC library, you must initialize the SX1262 with the correct regional band settings defined in the code. Always ensure your LoRaWAN network server (e.g., TTN, ChirpStack) is configured for the same region.
