BL651 Series
Bluetooth® 5 Low Energy Modules featuring
Nordic nRF52810
COST-EFFECTIVE BLUETOOTH 5 FOR SIMPLE BLE SOLUTIONS
Laird’s BL651 Series contains the latest Nordic
nRF52810 silicon with Bluetooth 5 Low Energy
capabilities and groundbreaking ultra-low power
performance. Building on Laird’s multi generation
module developments utilizing Nordic silicon
(BL600, BL652, BL654) – now comes the latest
series offering cost effective Bluetooth 5
enablement for simple BLE applications.
The BL651 series exposes all the capabilities of the
Nordic nRF52810 silicon in a small, fully certified
module with simple soldering castellation for easy
prototyping and mass production manufacturing.
Use the Nordic SDK and SoftDevice or Zephyr
RTOS to deliver your BLE application. Let Laird’s
innovative BL651 series and decades of expertise
in Bluetooth module design speed your product
to market.
In addition, the BL651 series is 100% PCB footprint
drop in compatible with the BL652 Series of
modules, allowing flexibility to upscale your
design if more flash/RAM or further feature sets
are required, during the design process.
