Description :

FUJITSU Component Wireless Module FWM7BLZ20 series is a compact wireless module corresponds to Bluetooth version 4.2. Its size is same as the Bluetooth version 4.1 enabled module MBH7BLZ02 series, though it achieves about half of the power consumption and about double the transmission distance. FWM7BLZ20 series embeds Nordic Semiconductor’s nRF52832 SoC. The module offers significant increase of user’s usable memory area and higher data transmission speed by improved processing power and enhanced memory size of embedded processor.

You can develop and embed your own application code by using SDK (Software Development Kit) and software stack provided by Nordic Semiconductor.

In addition, the module embeds NFC function to make it possible to connect NFC-enabled devices by using an external antenna.
