- Laird Connectivity BL653µ Nordic nRF52833 Module - Integrated antenna
Laird Connectivity BL653µ Nordic nRF52833 Modules target space-constrained applications to implement longer-range BLE in harsh operating environments. The BL653µ modules are low-power microcontrollers with multi wireless capabilities ideal for wireless Internet of Things (IoT) connectivity. The devices are powered by the Nordic nRF52833 Multi-Protocol System-on-Chip. They provide maximum development flexibility with programming options for the Nordic SDK or Zephyr RTOS, AT command set, and Laird Connectivity’s smartBASIC environment.
