KAGA FEI Co., Ltd., a leading global provider of short-range wireless modules, announced today the launch of the ES4L15BA1 Bluetooth low-power module.
This module adopts a built-in antenna and has passed multiple certifications. Therefore, it can reduce the development time and certification costs of next-generation wireless IoT products (such as IoT devices), small medical/healthcare products, and wearable devices that require a compact appearance, thereby accelerating product time to market.
ES4L15BA1 also supports channel detection for accurate distance measurement, providing further convenience for applications that require reliable distance information or enhanced security based on device distance information, such as unlocking devices based on their proximity.
In addition, it also supports PSA * 1 certification, which helps to develop IoT devices that meet advanced security requirements more easily. The mass production plan is scheduled to begin in September 2025. KAGA FEI will continue to respond to market demand and continuously expand its product lineup.
Product Features
The world's smallest compact appearance
ES4L15BA1 utilizes our proprietary technology to integrate into a 3.25x8.55x1.00mm external dimension as a Bluetooth 6.0 compatible antenna integration module, achieving the world's smallest size.
2. High processing power and large memory
ES4L15BA1 includes Arm Cortex-M33 processor, RISC-V coprocessor, 1.5MB non-volatile memory, and 256KB RAM, providing excellent processing performance and high processing efficiency.
3. Built in antenna and pre certified
Equipped with a built-in antenna, no antenna design is required. It has obtained Bluetooth qualifications and certifications from Radio Law MIC (Japan), FCC (United States), and ISED (Canada), which can reduce time and costs. In addition, it also supports Bluetooth SIG certification of the latest Bluetooth 6.0 standard, thereby supporting channel detection function to achieve accurate distance measurement.
