The Laird Technologies BL654 is a versatile and highly integrated wireless module designed to support Bluetooth® v5.1 along with NFC and 802.15.4 Thread capabilities, making it an ideal solution for modern IoT and smart device applications. Its compact footprint allows easy placement in space-constrained designs, while the option for either internal or external antennas gives engineers flexibility in optimizing wireless performance for different environments. With programmable transmit power ranging from +8 dBm to -40 dBm and excellent receiver sensitivity down to -103 dBm, it ensures stable long-range communication even in challenging RF conditions.
Built for efficiency, the BL654 delivers ultra-low power consumption in active and sleep modes, supporting peak currents of only 4.8 mA during transmission and 4.6 mA during reception. It offers a rich set of interfaces including UART, GPIO, ADC, PWM, I2C, SPI, USB, and more, enabling easy integration with sensors, controllers, and peripheral devices. Certified across major global regulatory bodies such as FCC, CE, IC, RCM, and Japan, the module simplifies product certification and speeds up time-to-market. Supported by multiple development options—including smartBASIC scripting and the Nordic SDK in C—the BL654 is well-suited for industrial, commercial, and consumer IoT solutions requiring high performance, low energy usage, and reliable wireless connectivity.
Nantian Electronics ensures ample availability of the BL654 and offers complete technical resources to support your procurement and design needs.
