Support the latest communication protocols: Based on BLUETOOTH® 5.3 LOW ENERGY standard development, can be compatible with Bluetooth 4.2-5.3 protocol, a wide range of compatibility, can be used for most products on the market.
Related certification: The module has completed the Bluetooth SIG BQB-5.3 authentication and declaration process, CE/RED (Europe), FCC (USA) and IC (Canada), EU-RED, SRRC and other certifications, which can serve various application scenarios in various regions of the world.
Low power design: Very low power standby mode, in the lowest power off mode, only 0.15UA of current consumption. It can wake up in a few microseconds, which is suitable for portable devices and wearable devices with strict power consumption requirements and timely response.
External IPEX antenna: The module reserves the IPEX antenna interface, which requires the use of external IPEX antenna, which also greatly improves the communication distance of the module. The communication distance between modules can be up to 248 meters (depending on the environment). The increase of communication distance can be applied to large-area networking, and the application field is further expanded.
High-performance processor: Integrated high-performance ARM CORTEX-M0+ processors provide enough computing power to support complex application scenarios. 80KB of available application code space, enabling customers to perform secondary development and embed complete applications.
Wide operating temperature range: adapt to the temperature of -40℃~125℃, can adapt to most of the natural environment, meet the temperature requirements of various application scenarios. It can also adapt to some extreme temperature application scenarios.
Rich hardware interface and scalability: Support UART/SPI interface, easy to communicate with MCU and data transmission. Up to 24 bidirectional programmable IO for external interrupt triggered input detection for a variety of input/output switching applications.
Small size design: Ultra-small size (11.59×17.9×2.0mm) for easy integration into a variety of small devices or compact devices.
Remote upgrade: Bluetooth slave version supports OAD (Over-the-Air Download) upgrade, and firmware can be updated without physical contact. The Bluetooth host version supports the Software Bootloader (SBL) upgrade, providing flexible upgrade channels.
Production capacity: automatic production line, production capacity is guaranteed.
