RAKwireless has launched the RAK11160 “WisDuo,” a new dual-core IoT module that integrates LoRaWAN, Wi-Fi, and Bluetooth Low Energy (BLE) connectivity into a single compact unit. Priced competitively at just $6.50 USD, the module is designed to serve a wide range of IoT applications from smart cities and agriculture to logistics and remote monitoring.
The RAK11160 is built using an STMicroelectronics STM32WLE5 microcontroller for sub-GHz LoRa communication and an Espressif ESP32-C2 chip for Wi-Fi 4 and BLE 5.3.
Its compact size of just 15 × 23 × 3 mm and ultra-low-power consumption make it ideal for battery-powered applications across diverse environments.
Key Features and Specifications
Multi-Radio Architecture
-
Dual-Core Setup: The STM32WLE5 manages LoRaWAN functions while the ESP32-C2 handles Wi-Fi and BLE communication. The two chips communicate via a UART interface, and the STM32 can power down the ESP32 to conserve energy when not needed.
-
Global LoRaWAN Support: Compatible with all major sub-GHz frequency bands including EU868, US915, AS923, IN865, and CN470.
-
BLE and Wi-Fi Support: Offers full 2.4 GHz wireless connectivity for local device management and updates.
-
Precision Clocking: Integrated TCXO ensures RF frequency stability over a wide temperature range of –40 °C to +85 °C.
-
Interfaces: Features UART with AT command support, I2C, SPI, ADC, and multiple GPIOs. Comes in two hardware variants: one with an MHF4 connector for external antennas and another with an RF pin-out.
Power Efficiency
- Sleep Current: Consumes just 2.8 to 5 µA in sleep mode when the ESP32-C2 is powered down.
- Optimized Firmware Modes:
-
-
Standalone Mode: The STM32 handles all tasks including LoRaWAN, BLE, and Wi-Fi.
-
Dual-Core Mode: LoRaWAN runs full-time, and Wi-Fi/BLE activates on demand.

Use Cases and Applications
Smart Agriculture and Remote Monitoring
The RAK11160 is suitable for long-term deployment in outdoor or remote areas where access to wired power is limited. Its LoRaWAN capability enables long-range data transmission, while Wi-Fi or BLE can be used for firmware updates and sensor calibration.
Asset Tracking and Logistics
In asset tracking systems, the module allows LoRaWAN to be used for wide-area monitoring while BLE provides local scanning and inventory control at distribution points.
Smart Cities and Infrastructure
Its multi-radio design enables flexible deployment in smart infrastructure solutions such as environmental monitoring, smart streetlights, and parking sensors. The combination of local and long-range communication enhances scalability and maintenance.
Developer Resources and Integration
RAKwireless provides full development support through its RUI3 SDK for the STM32WLE5 and the ESP-IDF or Arduino IDE for the ESP32-C2. Developers can choose to flash the STM32 directly or work with AT commands for rapid prototyping.
The module is compatible with most existing WisBlock and WisGate gateways by RAKwireless, simplifying integration for existing deployments.
Key Resources Include:
- Comprehensive datasheets
- RUI3 SDK with code samples
- AT command reference manual
- BLE and Wi-Fi integration tutorials
- Firmware update examples
Leadership Comments
Ken Yu, CEO of RAKwireless, commented on the launch:
“With the RAK11160, we’re redefining what affordable means in the world of multi-radio IoT. This module delivers long-range connectivity, efficient local communication, and outstanding battery performance—all in one compact package. It’s built to empower the next wave of smart, connected devices.”
Industry analysts also see this as a game-changing release. According to developers following LoRaWAN trends, combining an STM32WL core with an ESP32-C2 in a single unit at this price point is a long-awaited step toward truly integrated edge devices.
Product Variants and Market Availability
RAK11160 comes in two primary frequency variants:
-
RAK11160-H: For high-frequency LoRa bands (e.g., EU868, US915)
-
RAK11160-L: For low-frequency bands (e.g., IN865, CN470)
The module is currently available for bulk ordering through RAKwireless and select electronics distributors. Developers and prototyping teams can also purchase evaluation kits and development boards from RAK’s global storefronts.
