Acconeer XM122 IoT Module

Acconeer XM122 IoT Module features an optimized form factor used to support designs for commercial use, evaluation, and development purposes. The XM122 is built around the Nordic Semiconductor nRF52840 Bluetooth® 5 SoC (System on Chip). It features an integrated antenna for Bluetooth connectivity. The XM122 is used as a stand-alone module and can be embedded in application on top of the Acconeer RSS (Radar System Software). It can also be used with an external host controller where communication to the module is through a register command protocol.
