Entry+ Module XM125

Acconeer's Entry+ Module XM125 comes with the A121 60 GHz pulsed coherent radar sensor and a 32-bit Arm® Cortex®-M4 MCU. The XM125 module is optimized for high-precision people presence detection with the capability to recognize movement within configurable zones, motion detection, parking space occupancy detection, and level measurement in places such as tanks or waste containers with configurable update frequency. The module has been optimized for easy integration with land grid array (LGA) solder pad support, a small form factor of 18.6 mm x 15 mm, and a single-supply operating voltage of 1.8 V. The module is delivered with a bootloader which enables the customer to download the Acconeer radar system software (RSS) as well as the software development kit (SDK) for standalone usage, allowing the customer to embed their application on top of RSS software. The RSS software provides the API to set the A121 sensor configuration and to retrieve supported radar services and detector data. The RSS enables interfacing through an external host using a register command protocol over UART and I²C.
