Laird Connectivity has introduced a new series of BL653µ Bluetooth 5.1 modules, which delivers longer range Bluetooth Low Energy (LE) connectivity for harsh industrial operating environments in a footprint as small as 6.3 x 5.6 mm. Targeting space-constrained industrial IoT applications, the miniaturized BL653µ delivers secure, multi-protocol embedded wireless connectivity,
The BL653µ modules, powered by the Nordic nRF52833 SoC, offers several programming options, including the Nordic SDK or Zephyr RTOS, intuitive AT command set, or Laird Connectivity’s own smartBASIC environment. The nRF52833 hardware features and capabilities include USB access, up to +8 dBm transmit power, and up to 5.5-V supply range.

The BL653µ Bluetooth 5.1 modules feature direction finding with angle of arrival (AoA) and angle of departure (AoD), and an extended temperature range from -40° to 105°C. In addition, the modules have the potential to be Bluetooth 5.2 capable and offer hardware support for NFC and 802.15.4 (Thread and Zigbee).
Bluetooth meshing capabilities enable OEMs to extend the reach of messages by relaying them from node to node in a large group of connected devices. Bluetooth 5 long range (Coded PHY support) allow Bluetooth signals to travel further, enabling wireless communication for constrained, hard-to-reach equipment within factory floors and manufacturing plants, said Laird.
Modular FCC, IC, CE, RCM, MIC, and Bluetooth SIG approvals extend to an OEM’s design with no new testing required for faster time to market and reduced development risks.
