Introduction

Building on Laird’s expertise with Nordic from the BL654 series comes the most powerful yet - the BL654 PA series! It provides OEMs with the maximum design flexibility and performance. A complete multi - protocol embedded wireless offering with exceptional processing capability, all with extended PA / LNA support for even greater range. Powered by Nordic’s nRF52840 silicon, the small form factor BL654 PA modules and DVKs provide for a secure, robust BLE and Cortex - M4F CPU for any OEM’s product design. The BL654 provides you with maximum development flexibility with programming options for a simple, intuitive AT Command Set, as well as Laird’s own smartBASIC environment. The BL654 PA series brings out all nRF52840 hardware features and capabilities including USB access, up to 5.5V supply considerations, and builds in additional TX power capabilities via an integrated Skyworks PA. Complete regulatory certifications enable faster time to market and reduced development risk completes Laird’s simplification of your next Bluetooth design!
