As IoT applications continue to evolve, wireless connectivity is moving beyond the traditional requirements of low power consumption and long-range communication. Modern IoT devices increasingly need to support multiple frequency bands, communication protocols, higher data rates, and more flexible network options—often within a compact hardware design.
To address these requirements, MinewSemi introduces the ME26LS01, a multi-band wireless module built around Semtech’s fourth-generation LoRa transceivers and Nordic Semiconductor’s nRF54L15 high-performance, low-power MCU.
The ME26LS01 combines long-range connectivity, multi-band support, low-power operation, and multi-protocol capabilities in a compact 15 × 19 × 3.2 mm form factor. It is available in two hardware configurations: LR2021 + nRF54L15 and LR2012 + nRF54L15, giving developers greater flexibility when designing next-generation IoT products.
A growing number of IoT applications require more than one wireless technology. Depending on the deployment environment, a device may need long-range Sub-GHz communication, Bluetooth connectivity, Wi-SUN networking, or even satellite connectivity.
The ME26LS01 is designed to address these requirements through a multi-band, multi-protocol architecture.
Both versions support 150–960 MHz Sub-GHz operation, while the LR2021-based configuration additionally supports 2.4 GHz and S-band. The module also supports a range of IoT communication technologies, including BLE 6.0, LoRaWAN, Amazon Sidewalk, and Wi-SUN.
This architecture allows developers to select the connectivity combination that best fits their application instead of designing around a single wireless protocol.
· Sub-GHz: 150-960 MHz
· 2.4 GHz: Supported with the LR2021 configuration
· S-band: Supported with the LR2021 configuration
· BLE 6.0
· LoRaWAN
· Amazon Sidewalk
· Wi-SUN
· LR-FHSS and FLRC communication
· S-band satellite connectivity with the LR2021 configuration
The result is a flexible wireless platform suitable for applications that require different connectivity technologies across different deployment environments.
One of the key highlights of the ME26LS01 is its LR2021 + nRF54L15 configuration.
As a fourth-generation LoRa transceiver, the LR2021 maintains the long-range and low-power advantages associated with LoRa while extending its capabilities toward higher bandwidth and higher data-rate communication.
This opens up new possibilities for long-range wireless applications.
Traditional LoRa deployments are commonly associated with relatively small data payloads, such as sensor readings, device status information, and metering data. With higher data-rate capabilities, developers can explore a broader range of use cases where long-range wireless connectivity and greater data throughput are both important.
The ME26LS01 integrates the LR2021 with the nRF54L15, combining long-range wireless communication with powerful and energy-efficient processing in a compact module. The Sub-GHz transmit power reaches up to +22 dBm, while receive sensitivity can reach as low as -141 dBm, providing strong RF performance for demanding long-range applications.
The ME26LS01 is not limited to a single chipset configuration. MinewSemi offers two options based on different application requirements:
LR2021 + nRF54L15
The LR2021-based version is designed for applications that require higher data rates, broader frequency coverage, and S-band satellite connectivity.
Key capabilities include:
· 150–960 MHz Sub-GHz
· 2.4 GHz support
· S-band support
· Up to +22 dBm Sub-GHz transmit power
· Receive sensitivity down to -141 dBm
· BLE 6.0
· LoRaWAN and other IoT protocols
· S-band satellite connectivity
This configuration is particularly suitable for emerging IoT applications where traditional low-data-rate LoRa connectivity may no longer be sufficient.
LR2012 + nRF54L15
For developers looking to upgrade existing LoRa products while maintaining compatibility and controlling hardware costs, the LR2012-based configuration provides another option.
The LR2012 is a fourth-generation Plus LoRa transceiver designed to increase data rates while maintaining compatibility with established LoRa technology. It supports data rates of up to 125 kbps and offers SX1262-compatible replacement
capabilities. Its lightweight design can also help reduce BOM costs.
This makes the LR2012-based ME26LS01 particularly relevant for:
· SX1262-based product upgrades
· Drop-in or compatible product replacement
· LoRa product redesigns
· BOM cost optimization
Meanwhile, the LR2021 configuration is better suited to applications prioritizing higher bandwidth, higher data rates, and satellite connectivity.
Despite its broad connectivity capabilities, the ME26LS01 maintains a compact module size of only 15 × 19 × 3.2 mm.
Its RF performance is designed for long-range IoT deployments, with:
· Up to +22 dBm Sub-GHz transmit power
· Up to +12 dBm transmit power at 2.4 GHz/S-band
· Receive sensitivity down to -141 dBm
· Receive current as low as 5.9 mA
· Industrial-grade TCXO for frequency stability
The combination of high RF performance and compact size makes the module suitable for space-constrained IoT devices where communication range, power consumption, and PCB space all need to be considered.
The module also integrates the high-performance nRF54L15 Arm® Cortex®-M33-based MCU, providing processing resources for application development alongside wireless connectivity.
The ME26LS01 is designed not only as a LoRa module, but as a multi-protocol wireless platform.
Its support for technologies such as BLE 6.0, LoRaWAN, Amazon Sidewalk, and Wi-SUN enables developers to adapt the same hardware platform to different network architectures and application requirements.
This flexibility can be valuable in applications such as:
Long-range Sub-GHz connectivity can support communication with distributed meters, while Bluetooth can provide a convenient local interface for configuration, commissioning, or maintenance.
Remote environmental sensors can benefit from long-range, low-power connectivity, while multi-band support provides additional options for different deployment environments.
The module's long-range communication capabilities can help connect assets across large areas, while multiple wireless protocols provide flexibility for local and wide-area connectivity.
Large agricultural deployments often require wireless communication across wide outdoor areas. The ME26LS01 provides long-range Sub-GHz connectivity and multiple protocol options for different agricultural IoT architectures.
With S-band satellite connectivity available on the LR2021 configuration, the ME26LS01 can extend IoT connectivity beyond the reach of conventional terrestrial networks, opening possibilities for maritime transportation and other remote applications.
The development of IoT connectivity is moving toward greater protocol flexibility, broader frequency coverage, higher data rates, and wider network availability.
The ME26LS01 brings these capabilities together in a single compact module, combining Semtech’s fourth-generation LoRa technology with Nordic’s nRF54L15 platform.
With two chipset options, developers can select the configuration that best matches their product requirements:
LR2021 + nRF54L15 for higher bandwidth, multi-band connectivity, and S-band satellite applications.
LR2012 + nRF54L15 for SX1262-compatible upgrades, product redesigns, and cost-sensitive applications.
By supporting both established LoRa deployments and emerging higher-performance IoT applications, the ME26LS01 provides a flexible path from long-range, low-power connectivity to higher-data-rate and satellite-enabled IoT systems.
Whether you are developing a smart meter, environmental monitoring system, asset tracker, smart agriculture device, or remote connectivity solution, the ME26LS01 multi-band LoRa module provides a flexible hardware platform for building connected IoT products.
With Sub-GHz, 2.4 GHz, S-band, BLE 6.0, LoRaWAN, Wi-SUN, and satellite connectivity options, the ME26LS01 is designed to help developers build wireless devices that are ready for the next generation of IoT connectivity.
