BL653μ Series Bluetooth 5.1 + 802.15.4 + NFC Modules

Ultra-Compact and Highly Flexible

Ezurio's BL653μ Series modules bring reliable, high-quality Bluetooth 5.1 to their 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

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

Ezurio'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 Ezurio'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 Ezurio's simplification of your next small form factor Bluetooth design!

2. FlexPIFA™ antennas (patented)

Ezurio's FlexPIFA™ antennas (patented) are the industry's first flexible Planar Inverted-F Antennas (PIFA). The 2.4 GHz FlexPIFA™ is ideally suited for use with 2.4 GHz applications such as, Wi-Fi® 802.11 b/g/n and Bluetooth. The dual-band FlexPIFA™ is ideal for Wi-Fi applications across both bands, such as 802.11 'a'. Both the 2.4 GHz and dual-band 2.4/5.5 GHz FlexPIFA™ deliver strong performance in challenging environments, providing you unmatched flexibility to solve your real-world antenna design challenges.

The PIFA design provides consistent performance across a broad array of environments, enclosures, or even body-worn applications. With the ability to be flexed in either concave or convex directions, without sacrificing antenna performance, the small size and adhesive backing give further mounting flexibility within your product design.
