The IC is based on the Nordic semiconductor nRF52832 SoC, and provides ultra-low-power Bluetooth 5 connectivity in a small footprint. The nRF52832 SoC is powered by an Arm Cortex-M4 core supported by 512 Kbyte Flash, 64 Kbyte RAM and a 2.4GHz multiprotocol radio. The WSM-BL241 module adds a 32 MHz crystal, antenna, and extra pins to allow for the attachment of an NFC antenna and omnidirectional antenna. The small form factor module measures only 7.4 × 7.0 × 1.0 mm.
Development for applications using the module can be started immediately through the MBN52832 development kit, which is also available from Mouser, and the Nordic nRF52 SDK. The kit comprises 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.
