Description

The RAK3172 WisBlock LPWAN Module is a core wireless node built around the STM32WLE5CC system-on-chip, which combines an Arm Cortex-M4 microcontroller with a Semtech LoRa transceiver. This integration allows developers to execute application logic and manage long-range, sub-GHz LoRaWAN communication from a single, power-efficient chip. The module is pre-configured for the IN865 frequency plan, making it a ready solution for deployments in India and other regions using this band.

Out of the box, the module runs RAKwireless’s RUI3 firmware, an abstraction layer that simplifies coding by providing a unified set of AT commands and C++ APIs for handling LoRaWAN joins, data transmission, and power management. This significantly reduces development time compared to working directly with the LoRaMAC stack. The WisBlock form factor ensures easy integration; the module plugs directly into compatible WisBlock baseboards, providing immediate access to I2C, SPI, UART, ADC, and GPIO interfaces for connecting sensors and peripherals without complex soldering.

Key Features

  • Integrated MCU & LoRa Modem: The STM32WLE5CC SoC provides a 48MHz Cortex-M4 core and a Semtech SX126x-compatible LoRa transceiver in one package, reducing board complexity.
  • RUI3 Development Framework: Accelerate project timelines with a high-level API for network operations, sleep management, and peripheral control, compatible with the Arduino IDE.
  • Full LoRaWAN Protocol Support: Certified for LoRaWAN 1.0.3 specification, supporting Class A (mandatory), Class B (beacon-enabled), and Class C (continuously listening) device operation.
  • Optimized for IN865 Spectrum: Hardware is tuned for the 865-867 MHz band, adhering to regional duty cycle and transmission power regulations.
  • Modular & Expandable WisBlock Ecosystem: Snap this core module onto any WisBlock Base board to instantly create a complete sensor node or actuator controller.
  • Industrial-Grade Reliability: Designed for stable operation in extended temperature ranges, suitable for outdoor and harsh environment deployments.

Applications

  • Smart Agriculture: Soil moisture, temperature, and humidity monitoring across large farms with gateway connectivity.
  • Environmental Sensing: Deploying remote air quality, water level, or weather stations in areas without cellular coverage.
  • Asset & Logistics Tracking: Monitoring the location and condition of pallets, containers, or vehicles over wide geographical areas.
  • Industrial IoT (IIoT) Telemetry: Wireless collection of data from meters, pumps, or storage tanks in industrial facilities.
  • Smart City Infrastructure: Enabling connected waste management, smart parking, or streetlight monitoring systems.

Frequently Asked Questions

How do I start programming the RAK3172 module with the RUI3 framework?

Install the RAKwireless Arduino core via the Boards Manager in the Arduino IDE. Select 'RAK3172 (WisBlock)' as your board. Use the provided RUI3 APIs like `api.system` and `api.lorawan` in your sketch to manage sleep modes, read sensors, and send LoRaWAN packets without directly handling complex LoRaMAC stack functions. This abstraction significantly speeds up development.

What is the power consumption profile of the RAK3172 in deep sleep mode?

The RAK3172, leveraging the low-power modes of the STM32WLE5CC, can achieve deep sleep currents below 2 µA when peripherals are disabled. Actual consumption depends on your specific configuration, including retained GPIO states and the sleep duration set via the RUI3 `api.system.sleep()` function. For battery life calculations, measure current draw in your final application circuit.

Can I use this IN865 module with a LoRaWAN network server in another region?

No, the RAK3172 module variant specified is hardware-configured for the IN865 frequency band (865-867 MHz). It will not operate correctly on other regional bands like EU868, US915, or AS923. You must ensure your LoRaWAN gateway also supports the IN865 spectrum and that your network server (e.g., The Things Stack) is configured for the same region.

How do I connect external sensors to the RAK3172 WisBlock module?

You need a WisBlock Base board (e.g., RAK5005-O). Plug the RAK3172 into the module slot on the base. Sensors from the WisBlock ecosystem (e.g., RAK1901 temperature) connect via the dedicated sensor slots using the same plug-and-play connector. For custom sensors, use the pinout of the base board's IO slot, which breaks out I2C, SPI, UART, and analog pins.
