DreamLNK has officially released the DL-EFG23-B, a new industrial-grade Sub-GHz wireless transceiver module based on Silicon Labs' EFR32FG23 SoC. Designed to address the connectivity challenges of the Industrial Internet of Things (IIoT), smart metering, and smart city infrastructure, this RF module integrates long-range communication, ultra-low power consumption, and PSA Level 3 security into a compact, easy-to-deploy solution.
Built for Long-Range, Reliable Communication
At the core of the DL-EFG23-B is the EFR32FG23 wireless SoC, featuring an ARM Cortex-M33 processor running at up to 78 MHz, with 256 KB of Flash and 32 KB of RAM. The module operates in the Sub-GHz frequency bands (433/868/915 MHz), providing a clear advantage over the crowded 2.4 GHz spectrum. It delivers a maximum output power of +20 dBm and achieves an industry-leading receive sensitivity of -125.8 dBm at 915 MHz (4.8 kbps), enabling communication distances of up to 3 kilometers in open areas and stable penetration through 3 to 5 concrete walls.
"Interference from Wi-Fi and Bluetooth in the 2.4 GHz band is a persistent issue for industrial deployments," said a spokesperson from DreamLNK. "With the DL-EFG23-B, we offer a cleaner, more robust communication channel with superior penetration and diffraction capabilities, making it ideal for complex environments like factories and underground facilities."
Optimized for Battery-Powered, Long-Life Applications
The module's ultra-low power architecture is critical for remote sensors and battery-powered devices. It features a deep sleep current (EM2 mode) of less than 1 µA, facilitating a battery life of 3 to 10 years on standard lithium cells. This significantly reduces maintenance and replacement costs for large-scale deployments. The module also operates across a wide temperature range of -40°C to +85°C and supports a supply voltage of 1.7V to 3.8V, ensuring reliable performance in harsh outdoor or industrial conditions.
Comprehensive Multi-Protocol Support and Flexibility
A key differentiator of the DL-EFG23-B is its broad protocol compatibility. It supports standard protocols such as Wi-SUN, Amazon Sidewalk, WM-BUS, and Wirepas Mesh, alongside custom private protocol development. This versatility allows it to adapt to a wide range of applications, from city-scale smart grid networks to localized factory automation systems.
To accelerate product development, the module comes pre-loaded with a comprehensive AT command set, allowing for quick configuration and data transmission via a standard UART interface without the need for complex underlying driver development. For customers requiring deeper customization, DreamLNK provides a complete SDK and toolchain, enabling secondary development on the ARM Cortex-M33 core to implement complex business logic.
Financial-Grade Security for Critical Infrastructure
Security is paramount for industrial and metering applications. The DL-EFG23-B is equipped with Silicon Labs' Secure Vault technology and has achieved PSA Certified Level 3, the highest level of protection against both physical and remote attacks . It features a hardware cryptographic engine supporting AES, SHA, and ECC algorithms, secure boot, secure debug lock, and physical tamper detection. This ensures data integrity and prevents unauthorized access or firmware compromise.
A Future-Ready Solution for a Connected World
The DL-EFG23-B RF module is positioned as a future-proof solution for the expanding IoT ecosystem. Its combination of robust performance, low power consumption, and high security makes it suitable for a diverse range of applications, including:
Smart Metering: Wireless water, electricity, and gas meters requiring long life and reliable data transmission.
Industrial Automation: Monitoring critical equipment and enabling AGV communication.
Smart City: Streetlight control, manhole cover monitoring, and fire hydrant alarms.
Smart Agriculture: Remote soil monitoring and irrigation control in remote fields.
