Acconeer XM124

The Entry + Module XM124 is an integration ready Land Grid Array (LGA) module for compact commercial products that measures 18.6x15 mm. Optimized for use cases such as smart people presence, motion detection, parking space occupancy detection, and level measurement for example in tanks or waste containers. The XM123 is an integration ready Land Grid Array (LGA) module for compact commercial products that measures 18.6x15 mm. Dedicated for smart people presence and motion detection only. The XM124 and the Entry + Module XM123 is built around the Arm 32-bit Cortex -M4 MCU from STMicroelectronics (STM32L431CBY6) and can be used as a stand-alone module where customer can embed their 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 executed via a register command protocol. The Entry + Modules XM123 and XM124 comes with the A111 60 GHz PCR sensor and a 32-bit ARM Cortex M4 MCU. The two variants have the same PCB but different component mounting options. The resistors R3 and R4 identify the two different variants. The XM124 module is optimized for high precision people presence detection with capability to recognize movement within configurable zones, motion detection, parking space occupancy detection and level measurement for example in tanks or waste containers with configurable update frequency. The XM123 module is a cost sensitive limited variant supporting the Acconeer Sparse Service which is suitable for applications such as people presence and motion detection. The modules have been optimized for easy integration with LGA solder pads support, a small form factor of 18.6x15 mm and single supply operating voltage 1.8 V. The modules are delivered with a bootloader which enables the customer to download the Acconeer Radar System Software (RSS) software as well as the SDK (Software Development Kit) for standalone usage where the customer can embed their own application on top of RSS software. The RSS software provides the API to set A111 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.
