Building on Laird Connectivity’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 Connectivity’s own smartBASIC environment.

  • Bluetooth v5 Low Energy (BLE) + NFC
  • Integrated Skyworks Power Amplifier - Up to +18 dBm output
  • Ultra-small footprint - 15 mm x 10 mm x 2.2 mm
  • 2 Mbps and LE Long Range

More power so you can go farther. 

The BL654 PA features an onboard power amplifier that doubles the output power to as high as 18 dBm, over twice the power of the original BL654 Series. High output power and LE Long Range mean roughly double the range for your Bluetooth applications. 

  • Utilizes Skyworks part # SKY6612-11
  • Provides + 10dBm more than standard BL654 (part # 451-0001 / 451-00002)
  • Range of external antennas certified
  • Complete power control with onboard smartBASIC FW image
