BL54L Bluetooth LE Series

Introducing our BL54L series, our latest Bluetooth LE solutions powered by Nordic Semiconductor's cutting-edge nRF54L series chipsets , offering unparalleled performance, security, and efficiency.

  • The BL54L15 Series elevates connectivity with its powerful processing, expanded memory, and comprehensive security features, all within a compact module designed for flexibility.
  • The BL54L15µ Series is the same as the BL54L15 series, but in an even more compact 6.3 x 7.9 x 1.6 mm form factor.
  • The BL54L10 Series provides a reduced flash and RAM option in comparison to the BL54L15, all in the same footprint. 
  • The BL54LM20A and BL54LM20B provides the greatest amount of flash and RAM, plus an optional Edge AI NPU (BL54LM20B) and the pluggable BL54LM20B USB-C Adapter.

The BL54L series ensure secure, robust, and efficient wireless communication with support for the latest Bluetooth standards and secure programming options.
