The WSM-BL241 Bluetooth low energy module from Murata is available at Mouser Electronics. It is based on a Nordic nRF52832 system-on-chip (SoC), and offers ultra-low-power Bluetooth 5 functionality in a small package, ideal for Internet of Things (IoT), asset-tracking, beacon, and medical applications.
The module leverages the SoC to provide high-performance Bluetooth low energy connectivity between smartphones, tablets, and other devices. The low-power nRF52832 SoC combines a built-in Arm Cortex-M4 core, 512Kbytes of flash, and 64Kbytes of RAM with a 2.4GHz multiprotocol radio.
The WSM-BL241 module includes a 32MHz crystal, on-board antenna, and two pins for an NFC antenna and external omnidirectional antenna—all in a form factor of just 7.4 × 7.0 × 1.0mm.
The module is supported by the MBN52832 development kit, also available from Mouser. This facilitates application development using the Nordic nRF52 software development kit (SDK).
The kit consists of two separable modules: an interface module with J-Link USB-SWD and USB-UART interfaces, and a breakaway module with the onboard WSM-BL241 module with NFC antenna to support evaluation of Bluetooth- and NFC-based networking products.
