Pain Points and Breakthroughs in the Popularization of mmWave Sensing

Current smart sensing solutions face three major challenges:

  1) Oversized Components: PIR modules and 5.8GHz microwave modules are too large to fit into compact devices;

  2) High Costs: Traditional mmWave radar remains expensive, hindering its adoption in cost-sensitive consumer products;

  3) Technical Barriers: Development relies on specialized radar expertise, limiting large-scale applications due to high entry barriers.

To address these issues, Possumic Technology Co., Ltd. today launched two key products simultaneously: the 24GHz AoB mmWave module MRS251 and the radar sensing chip RS2111FD, providing a complete sensing solution through both module and chip offerings. This marks a dual breakthrough in cost efficiency and miniaturization for Possumic's 24GHz mmWave technology, clearing obstacles for the widespread adoption of mmWave radar sensors in smart devices.

I. Product Portfolio: Module and Chip Launched Together

1. MRS251 AoB Module: A Cost-Effective System-Level Solution

  • Cost Revolution: First to achieve price parity with mainstream 5.8GHz/10GHz microwave sensors and PIR modules, significantly lowering the barrier to 24GHz mmWave adoption.

  • Plug-and-Play: Integrated design enables rapid deployment, drastically shortening development cycles for smart devices.

2. RS2111FD Sensing Chip: A Benchmark in Chip-Level Miniaturization

  • Ultra-Compact Integration: Industry's smallest package (2.5×2.5mm QFN), with built-in MCU, Flash, and full interfaces, overcoming integration challenges in space-constrained devices.

  • Flexible Applications: Serves as the core sensing engine for compact, ultra-thin, and narrow-bezel designs, enabling deep hardware optimization.

3. Dual-Value Proposition: Flexible Selection Based on Needs

  • Module: Ideal for fast mass production with reduced R&D investment.

  • Chip: Designed for extreme space savings and customization.

  • Advantage: Allows solution providers and end customers to customize antenna designs and module dimensions freely.

II. MRS251 Module: Six Major Technical Advantages Define a New Industry Standard

Module Compatibility: The MRS251 is hardware pin-to-pin compatible with modules like the MRS261L and MRS262, supporting seamless customer solution replacement and iteration.

III. Mass Production & Ecosystem Support

  • Mass Production Status: The MRS251 module (based on the RS2111FD chip) is now in official mass production.

  • Development Support: We provide templates, development boards, evaluation and development tools, along with a complete set of technical documentation.

  • Purchasing Channel: Available in stock via Possumic's authorized Taobao store.

Conclusion

By delivering the MRS251 module and RS2111FD SoC together, Possumic has built a complete technology stack covering both system‑level solutions and core chips. Breakthroughs in cost‑performance, miniaturization, power efficiency, and global compliance will accelerate the large‑scale adoption of 24 GHz mmWave technology in motion detection, driving the popularization of intelligent sensing.
