![LB-LINK BL-M8821CS1 Wireless Module: Low Power Dual-Band for Robot Vacuums]()
Solving 3 Core Challenges of the Robot Vacuum Industry
With the booming development of the smart home track, robot vacuums are accelerating towards thinner, smarter, and longer-lasting battery life. However, behind the industry upgrade lie three core contradictions: the miniaturization of the body leads to extremely compact internal space, making traditional wireless modules difficult to adapt; intelligent interaction relies on stable wireless communication, but high-power modules exacerbate battery life pressure; alternating high and low temperatures in home environments easily cause module disconnection, affecting user experience.
Targeting these industry pain points, LB-LINK launches the BL-M8821CS1 wireless communication core solution—integrating ultra-small size, dual-band stable connection, low power consumption, and strong environmental adaptability. It provides stable and reliable wireless communication support for the robot vacuum industry, enabling uninterrupted long-term cleaning and empowering all-round product upgrades.
Ultra-Small Size, Unbounded Compatibility: Meeting Thin & Light Design Needs
As robot vacuums evolve towards miniaturization and thinness, their internal structures become increasingly compact, imposing strict requirements on the size of core components. The BL-M8821CS1 adopts an extremely streamlined design with a volume of only 12×12×2.4mm (note: corrected from potential formatting error in original text, consistent with "coin-sized" description). This core module, as small as a coin, can be easily embedded in space-constrained embedded devices without modifying the original body design. It perfectly meets the structural needs of small and thin robot vacuums, making product design more flexible.
Low Power Consumption & Stable Connection, Worry-Free Battery Life: Supporting Long-Term Efficient Work
Long battery life is the core competitiveness of robot vacuum-mop combos, and the power consumption of wireless modules directly affects device battery performance. The BL-M8821CS1 focuses on low-power technology, with an operating power consumption of ≤420mA. Equipped with an efficient energy management design, it significantly reduces power loss, providing long-lasting power support for battery-powered portable devices. This frees robot vacuum-mop combos from the trouble of "frequent charging" and enables long-term continuous cleaning.
Meanwhile, the module supports 2.4/5GHz dual-band and WiFi 5 standard, with a speed of up to 433Mbps. Adopting a 1T1R 802.11a/b/g/n/ac WiFi + BT4.2 dual-mode design, it achieves high-speed and stable transmission for both APP remote control of smart planned robot vacuums and real-time synchronization of cleaning paths, eliminating communication delays or disconnections.
Wide Temperature Adaptation, Full-Scenario Coverage: Coping with Complex Home Environments
Temperature fluctuations in home environments are significant. Low temperatures in cold winters and high temperatures in scorching summers may affect the stability of wireless modules. The BL-M8821CS1 features a -20℃~70℃ wide operating temperature range. With strong environmental tolerance, it easily copes with various extreme temperature change scenarios, ensuring that robot vacuums maintain stable connections in different seasons and rooms, so the cleaning experience is not affected by the environment.
4 Additional Advantages to Accelerate Product Launch & Mass Production
In addition to solving core pain points, the BL-M8821CS1 provides comprehensive landing support for enterprise customers, reducing R&D and production costs:
• Low system adaptation cost: Compatible with mainstream Linux/Android systems, it can directly connect to mainstream motherboards on the market, greatly reducing adaptation workload and shortening product R&D cycles;
