Five Major Features
01
Integrated Master-Slave
The HLK-B26 is a BLE 5.0 integrated master-slave Bluetooth serial transparent transmission module developed and produced by Hailin Technology. Various devices with serial ports can easily and quickly use this module for Bluetooth wireless data transmission.
Meanwhile, the B26 can be set to operate as either a Bluetooth slave device or a master device, with the master mode supporting connection to 1 slave and the slave mode supporting a maximum of 1 master connection.
02
Ultra-Low Power Consumption
The power consumption of the HLK-B26 Bluetooth module is as low as microamp level, with a sleep current of 102μA, supporting customizable connection and broadcast intervals.
Power consumption (in a single state) is Bluetooth TX current (0dB) 5.7mA, Bluetooth RX current 5.5mA, and average sleep current 102.3μA.
With microamp-level power consumption and ultra-small size, it effectively addresses the power supply issues encountered in long-term use of IoT Bluetooth devices, where a standard button battery can power the device for many years.
03
BLE 5.0 Bluetooth
The HLK-B26 Bluetooth module supports BLE 5.0, offering fast transmission speed, high sensitivity, and long propagation distance, with a wide range of application scenarios.
BLE Bluetooth 5.0 introduces technological improvements at the physical layer, including a 2x increase in speed, a 4x increase in range, and an 8x increase in broadcast data capacity. It also introduces low-energy broadcast and connection modes, as well as a new 2Mbps high-speed data transmission mode.
04
Transmission Distance 40-60m
The HLK-B26 Bluetooth module has adjustable transmission power, up to 8dBm, with a receiving sensitivity of -92dBm, achieving a transmission distance of 40-60 meters in open environments.
Meanwhile, the mesh networking capability of the B26 is currently in the testing phase, and once this feature is launched, the transmission range will significantly increase.
05
OTA Bluetooth Wireless Upgrade
The HLK-B26 Bluetooth module supports OTA Bluetooth wireless upgrades of module firmware and wireless configuration of module parameters, which can be tested using the B40 testing suite and the B40 APP.
Additionally, the B26 has a fast networking speed and can quickly be tested using Hailin Technology’s mobile Bluetooth transparent transmission testing APP.
Application Scenarios
01
Smart Home Appliances
The HLK-B26 features low power consumption, low cost, and fast networking speed, making it widely applicable in smart home appliance products.
By utilizing Bluetooth technology for wireless connection and data interaction with smartphones, ordinary smart home appliances can be controlled via smartphones, such as smart sockets, smart lights, and smart locks.
02
Instruments and Meters
The B26, with its wireless transmission, stable signal transmission, low power consumption, and high cost-performance ratio, is highly suitable for instruments and meters.
Instruments and meters that integrate the B26 can reliably read and monitor data without being affected by external environments.
03
Agricultural and Industrial Control
Smart devices in agriculture and industry are widely used and require energy efficiency and low cost, making the low-cost, low-power Bluetooth module B26 very suitable.
By using the B26 for wireless connection to various control or sensing smart agricultural and industrial devices, data reading and control can be achieved.
The HLK-B26 features an integrated master-slave design, BLE 5.0 Bluetooth, high cost-performance ratio, ultra-low power consumption, easy development, and fast testing, with a wide range of applications. Currently, the price for the first sample is only 1 yuan, with limited availability. Interested friends should hurry!
