Description

The Elecrow nRFLR1110 Wireless Transceiver Module is a highly integrated solution combining the processing and short-range wireless capabilities of the Nordic Semiconductor nRF52840 with the sub-GHz long-range power of the Semtech LR1110. This architecture enables a single module to handle complex IoT tasks, from secure LoRaWAN Class A/B/C communication over distances up to 10km to local Bluetooth Mesh networking and precise geolocation.

Engineered for ultra-low-power operation, the module features a deep sleep current of just 6µA, making it a cornerstone for solar-powered or long-life battery deployments in smart agriculture, asset tracking, and environmental monitoring. Its support for global ISM bands from 850MHz to 930MHz ensures compliance and interoperability across different regional LoRaWAN networks.

The module’s compact 20x20mm footprint and comprehensive feature set, including NFC and Thread protocol support, provide system integrators and developers with a versatile foundation for building next-generation LPWAN and wireless mesh solutions without the complexity of managing multiple discrete RF components.

Frequently Asked Questions

How do I program or configure the nRFLR1110 module?

The module comes pre-loaded with AT command firmware accessible via its UART interface (default baud rate typically 115200). You can configure LoRaWAN parameters (DevEUI, AppKey), set GNSS modes, and control BLE using simple ASCII commands. For advanced custom firmware, you can develop using Nordic Semiconductor's nRF Connect SDK or Zephyr RTOS, targeting the nRF52840 core and utilizing its libraries to control the connected LR1110 chip via SPI.

What is the power supply requirement and how do I achieve the 6µA sleep current?

The module operates from a single-cell Li-ion or LiPo battery with a voltage range of 1.8V to 3.7V. To achieve the specified 6µA deep sleep current, you must properly configure the nRF52840 into its System OFF or lowest power sleep mode using firmware. Ensure all unused GPIOs are set to a defined state (output low/high or input with pull) and that the LR1110 sub-GHz radio is also put into its hibernation or sleep mode via command before entering the MCU's deep sleep.

Can I use an external antenna for better LoRa or GNSS performance?

Yes, the module's PCB layout includes pads for connecting external antennas. For LoRa, you can solder a wire or connector to the designated RF_OUT pad, ensuring impedance matching to 50 ohms. For the GNSS functionality on the LR1110 chip, an external active GNSS antenna can be connected to its dedicated RF_IN_GNSS pad, requiring a 3.3V bias tee to power the active antenna element. Always refer to the official pin definition diagram for exact pad locations.
