BL654 Series
Bluetooth v5 + 802.15.4 + NFC Modules & Adapter
BL653µ Series
Bluetooth® + 802.15.4 + NFC Modules
ROBUST RELIABLE BLUETOOTH CONNECTIVITY FOR IOT – JUST SMALLER
Laird Connectivity’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 BLE 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.
Powered by Nordic’s nRF52833 WLCSP silicon, the small form factor
BL653µ modules provide for a secure, robust Bluetooth Low Energy and
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
Laird Connectivity’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 Laird Connectivity’s simplification of your next
small form factor Bluetooth design!
