HLK-B50S Product Features
Ultra-small size, ultra-high performance
Small size, large capacity. The HLK-B50S Bluetooth module is compact, measuring only 27*13*2mm. Despite its small size, it boasts powerful performance with a built-in 32-bit ARM Cortex M3 core, operating at a frequency of up to 48MHz.
BLE5.3 Dual-Mode Bluetooth
The HLK-B50S Bluetooth module is an upgraded version of the B50 Bluetooth module, featuring technological upgrades and improved cost-performance ratio, with a lower unit price.
The B50S module supports BR/EDR and BLE5.3 dual-mode Bluetooth, incorporating both classic Bluetooth and low-energy Bluetooth standards, suitable for various scenarios such as audio transmission and intermittent data transmission.
Master-Slave Integrated Long-Distance Transmission
The HLK-B50S Bluetooth module is primarily used for fast Bluetooth wireless data transmission between devices, achieving a transmission distance of up to 80 meters in open environments.
The module supports BLE master-slave integration, allowing it to be configured as either a BLE slave device or a master device. By utilizing the bidirectional serial-Bluetooth transmission function of this module, users do not need to understand complex Bluetooth protocol stacks; they simply connect their device or MCU’s serial port to this module, which will automatically complete bidirectional data forwarding between the serial and Bluetooth (GATT or SPP), with GATT and SPP able to connect simultaneously.
Rich Pins, Simple Applications
The HLK-B50S Bluetooth module features a rich set of output pins, including UART, I2C, SPI, GPIO, ADC, PWM, I2S, etc., providing flexible and in-depth software and hardware customization development services. Additionally, the module offers a testing suite for users to quickly validate their designs.
HLK-B50S Product Feature Application Scenarios
Smart Home/Appliances
The HLK-B50S Bluetooth module can be widely used in smart sockets, smart lights, smart locks, curtain controllers, and other devices. Users can utilize the B50S Bluetooth module to directly control device switches, adjust brightness, or lock doors through an app, achieving intelligent control of ordinary appliances.
IoT (Internet of Things) Data Interaction
The HLK-B50S Bluetooth module can be widely used in the IoT industry, such as for communication between sensor nodes and gateways, or between industrial PLCs and HMI screens. The module’s built-in MCU can directly process sensor data, reducing the cost of external microcontrollers, while its compact size and high cost-performance ratio make it easy to apply.
Instrumentation and Parameter Configuration
The HLK-B50S Bluetooth module can be widely used in electric power meters and gas detectors, transmitting real-time data to mobile phones or tablets via Bluetooth, replacing traditional wired connections.
