A121 60GHz Pulse Coherent (PCR), integrating RF, baseband, and AiP antennas, supports human presence, micro-motion, and high-precision ranging
Integrated with an Arm Cortex-M4 MCU (STM32L431CBT6), 80MHz, 128KB Flash and 64KB RAM, supporting local processing
10 Interfaces support 3.3 V
Supports installation through plastic or glass; the product can operate reliably without requiring additional drilling
Reserved PCB SWD test points to facilitate RSS and user application development, production programming and testing

The A121 Range Sensor is a distance sensor based 60GHz pulsed coherent (PCR) technology, enabling human presence and motion detection and supporting high-precision distance measurement. It features good anti-interference capabilities through configurable detection area and sensitivity parameters. The module integrates an Arm Cortex-M4 MCU (STM32L431CBT6), allowing it to be deployed directly as a standalone unit Acconeer RSS for user applications, or to communicate with an external host controller via register command protocol. Its small size, low power consumption, and ease of integration make it suitable for applications such as human presence detection, proximity sensing, non-contact triggering, and vital sign monitoring
