Laird Connectivity BL653μ modules

Laird Connectivity’s BL653µ modules are suitable for harsh environments and space-constrained applications, delivering long-range Bluetooth Low Energy with NFC. The devices’ multi-wireless capabilities make them useful for a range of Internet of Things (IoT) applications, including secure medical peripherals, professional lighting and industrial IoT sensors.

The minuscule, highly integrated modules are powered by the Nordic Semiconductor nRF52833 multi-protocol system-on-chip (SoC), with an Arm Cortex-M4F CPU plus 512 KB of flash and 128 KB of RAM for demanding product designs. The modules offer high development flexibility with support for the Nordic SDK or Zephyr RTOS, AT command set and Laird Connectivity’s smartBASIC environment.

The smallest device is only 6.3 x 5.6 mm, offering good low-power performance and support for a wide range of configurable interfaces, including UART, I²C, GPIO and USB. Featuring Bluetooth 5.1 mesh capabilities as well as direction finding with angle of arrival and angle of departure, the modules provide high performance in challenging RF wireless and Industrial IoT applications.
