The low-power module has an outline of 15.7 x 9.8 x 1.7 mm, and is Bluetooth 4.2 enabled. The nRF52832 QFN-package wireless module has been designed around a 32-bit ARM Cortex-M4F CPU with 512 kB + 64 kB RAM. The embedded 2.4 GHz transceiver supports Bluetooth Smart, ANT and proprietary 2.4 GHz protocol stack. It is on air compatible with the nRF51 Series/modules. Thirty GPIO pins are available.
NFC-A tag support is included on chip and out-of-Band (OOB) pairing using NFC simplifies the process of authenticated pairing between two Bluetooth devices by exchanging authentication information over an NFC link. The module features two built-in crystal oscillators 32 MHz and 32.768 kHz. Fujitsu Components has a design team dedicated to antenna development able to match module capabilities to proven antenna quality. As-deliverd, the nRF52 based wireless module will be FCC/IC/CE/Japan radio ACT certified.
