Description

The RAK3172 Evaluation Board is a comprehensive development platform designed for engineers and system integrators building long-range IoT networks. At its core is the STM32WLE5CCU6 system-on-chip, which integrates an ARM Cortex-M4 processor with a Semtech SX126x-based LoRa transceiver, enabling both LoRaWAN protocol stack execution and direct P2P communication. This architecture provides a balance of processing power and ultra-low-power RF performance, suitable for battery-operated field deployments.

The board’s RF front-end supports a wide spectrum of global sub-GHz ISM bands, allowing for seamless regional deployment. It includes a comprehensive power management unit supporting USB-C, a single-cell Li-Ion battery, and direct solar panel input with MPPT, facilitating operation in off-grid environments. With 256 KB of Flash and 64 KB of SRAM, developers have ample space for custom application logic and Over-the-Air (OTA) updates.

Key Features

  • Integrated STM32WLE5CCU6 SoC combining Cortex-M4 MCU and Semtech SX126x LoRa transceiver.
  • Full compliance with LoRaWAN 1.0.3 specification and support for raw LoRa point-to-point mode.
  • Global multi-band RF support for worldwide LoRaWAN network deployment.
  • Advanced power system with USB-C, battery charging circuit, and solar panel MPPT input.
  • Development flexibility with RAK Unified Interface (RUI3) Arduino core and AT command set.
  • Expansive I/O header exposing multiple GPIOs, ADCs, UARTs, I2C, and SPI interfaces.
  • Robust operating temperature range from -35°C to 70°C for harsh environments.
  • On-board USB-to-serial converter for easy programming and serial debugging.

Applications

  • Smart agriculture for soil moisture monitoring, livestock tracking, and automated irrigation control.
  • Industrial IoT (IIoT) for remote telemetry, equipment condition monitoring, and predictive maintenance.
  • Environmental sensing networks measuring air quality, water levels, and weather parameters.
  • Asset tracking and logistics for pallet, container, and vehicle location monitoring.
  • Smart city infrastructure for waste management, parking space monitoring, and streetlight control.

Frequently Asked Questions

How do I program the RAK3172 Evaluation Board using the Arduino IDE?

First, install the RAKwireless Arduino BSP by adding 'https://raw.githubusercontent.com/RAKwireless/RAKwireless-Arduino-BSP-Index/main/package_rakwireless_index.json' to your Additional Boards Manager URLs. Then, search for and install the 'RAKwireless RUI3 STM32 Boards' package. Select 'RAK3172 Evaluation Board' as your target, connect via USB, and choose the correct COM port to upload your sketches, leveraging the RUI3 APIs for LoRaWAN functionality.

What is the procedure for configuring the board for LoRaWAN operation via AT commands?

Connect the board to a serial terminal (e.g., PuTTY) at 115200 baud, 8N1. Use AT commands like 'AT+NWM=1' to set LoRaWAN mode, 'AT+BAND=Your_Region_Code' (e.g., 'US915') to set the frequency band, and 'AT+JOIN=1,0,8,0' to start an OTAA join procedure. Ensure your DevEUI, AppEUI, and AppKey are correctly set using AT+DEVEUI, AT+APPEUI, and AT+APPKEY commands prior to joining the network.

How do I connect a solar panel to power the RAK3172 board in the field?

Connect the positive and negative leads of your solar panel (6-12V recommended) to the dedicated 'SOLAR' screw terminal on the board. The integrated power management unit includes an MPPT charger to efficiently charge the connected Li-Ion battery. Ensure the battery is connected to the 'BAT' terminals. The system will automatically prioritize solar power when available and switch to battery power when solar input is insufficient.

What antenna should I use, and how is it connected for optimal range?

Use a LoRa-specific antenna tuned to your operating frequency band (e.g., 868MHz for EU868). The board has an SMA female connector. Screw the antenna's SMA male connector firmly onto it. For the claimed 15 km range, ensure you use a high-gain antenna (e.g., 3-5 dBi) mounted outdoors with a clear Line-of-Sight (LoS). Avoid placing the antenna near large metal objects or enclosures that could detune the RF performance.
