Fanstel BM20x Nordic nRF54LM20x BLUETOOTH® 6.0 Modules
Fanstel BM20x Nordic nRF54LM20x BLUETOOTH® 6.0 Modules are compact, fully integrated wireless connectivity solutions based on Nordic Semiconductor's advanced nRF54LM20A and nRF54LM20B system-on-chip (SoC) platforms. Designed to accelerate the development of Bluetooth Low Energy (BLE), Thread, Zigbee®, and proprietary 2.4GHz wireless applications, the BM20x family combines a high-performance 128MHz Arm® Cortex®-M33 processor, 2036KB of flash memory, 512KB of RAM, integrated RF circuitry, and onboard crystals in a pre-certified module format that minimizes design complexity and time to market. Select models featuring the nRF54LM20B add an integrated Axon Neural Processing Unit (NPU), enabling edge AI capabilities for intelligent sensor processing and reduced cloud dependency.
The Fanstel BM20x series supports Bluetooth 6.0, IEEE 802.15.4 for Thread and Zigbee networks, and proprietary wireless protocols, with data rates of up to 4Mbps, receive sensitivity down to -106dBm, and programmable transmit power levels from ±8dBm. Advanced security features include secure and non-secure memory protection, cryptographic accelerators, secure key management, tamper detection, and immutable boot protection. Available in multiple antenna configurations, including chip, PCB, and external antennas, as well as power-amplified variants, the modules provide flexibility for a broad range of Internet of Things (IoT), industrial automation, smart building, asset tracking, healthcare, wearable, and edge AI applications. Operating from 1.7V to 3.6V and qualified for temperatures ranging from -40°C to +125°C, the BM20x modules deliver a robust, low-power wireless platform for next-generation connected devices.
