Laird Connectivity’s latest range of Nordic nRF52833 based modules specifically targets OEMs where space is constrained in their designs.  Yet still the **miniaturized BL653µ series** enables Industrial OEMs to robustly implement **longer range** BLE applications in the **harshest operating environments** . This series of secure, low power microcontroller modules with multi wireless capabilities is the future of wireless Internet of Things (IoT) connectivity. 

Powered by **Nordic’s nRF52833 WLCSP** silicon, the small form factor BL653µ modules provide for a secure, robust Bluetooth Low Energy and **Cortex -M4F** CPU for any OEM’s product design. The BL653µ provides you with maximum development flexibility with programming options for the **Nordic SDK** or **Zephyr RTOS** , a simple, intuitive **AT command set** , as well as Laird Connectivity’s own _**smart**_ **BASIC** environment. 

The BL653µ series brings out key nRF52833 hardware features and capabilities including **USB access,** up to **+8 dBm** transmit power, up to **5.5V** supply considerations, and **NFC tag (type 2 / 4)** implementation. Complete regulatory certifications enable faster time to market and reduced development risk completes Laird Connectivity’s simplification of your next small form factor Bluetooth design!
