Modules support long-range BLE applications in harsh environments

07-07-2020 | Mouser Electronics | Subs & Systems

Mouser now stocks the BL653 Series of modules from Laird Connectivity. Providing a wide range of configurable interfaces and an extended industrial temperature rating, the modules offer reliable Bluetooth 5.1 connectivity and support for NFC and 802.15.4 communication (Thread and Zigbee) for a variety of IoT applications in industrial settings and other harsh environments.

The modules are small modules that provide Bluetooth 5.1 connectivity, multi-wireless capabilities, longer range, and an extended temperature range up to 105C. Powered by the compact Nordic nRF52833 SoC, BL653 modules benefit from the SoC’s 64MHz Arm Cortex-M4 with FPU, high output power of up to +8dBm, and exceptional sensitivity of -95dBm sensitivity in 1Mbps.

The modules provide Bluetooth 5.1 including direction finding with AoA and AoD, as well as long-range (Coded PHY) and 2M PHY support for data rates of 2Mbps, 1 Mbps, and 125 Kbps. The 15mm x 10mm x 2.2mm modules also support flexibility in application design, allowing developers to decide between the company’s smartBASIC, simple AT command set, Nordic SDK, or Zephyr RTOS. The module family comprises integrated PCB trace antenna options for overall design simplicity or Trace Pad versions for connecting a variety of pre-certified internal and external antenna options.

The device comprises modular FCC, IC, CE, RCM, MIC, and Bluetooth SIG approvals, which spread to an OEM’s design without new testing for the quickest route to production. Design engineers can take advantage of the fully-featured development kit, offered with either an internal antenna or a variety of pre-certified external FlexPIFA antenna, which gives the essential tools to begin Bluetooth Low Energy development.
