BL653μ Series - Bluetooth 5.1 + 802.15.4 + NFC Modules

Under Development

Overview

Reliable Bluetooth Connectivity for the IoT - Just a Fraction of the Size. 

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 Bluetooth LE 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, as small as 6.3 x 5.6 mm

Powered by Nordic’s nRF52833 WLCSP silicon, the small form factor BL653μ modules provide for secure, robust Bluetooth Low Energy and a 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 smartBASIC 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!

Ultra-Compact and Highly Flexible

Our BL653μ Series modules bring reliably, high-quality Bluetooth 5.1 to our smallest form factor ever. With an optional chip antenna or antenna trace pin, they provide multiple ways to connect and develop at an incredibly small size. 

  • Chip Antenna (453-00059) - 6.3 x 8.6 x 1.6 mm
  • Trace Pin (453-00060) - 6.3 x 5.6 x 1.6 mm
