X-NUCLEO-WB05KN1

The X-NUCLEO-WB05KN1 expansion board provides Bluetooth^® Low Energy connectivity for developer applications and can be plugged into an STM32 Nucleo development board (for example NUCLEO-U575ZI-Q) through its ARDUINO^® Uno V3 connectors.

The expansion board features Bluetooth^® v5.4 compliant and FCC‑certified STM32WB05KN. This SoC manages the complete Bluetooth^® Low Energy stack and protocols on its Arm^® Cortex^®‑M0+ core and programmable flash memory. STM32WB05KN supports central and peripheral modes and increased transfer rates with data length extension (DLE).

X-NUCLEO-WB05KN1 interfaces with the STM32 Nucleo microcontroller via UART (default) with and without hardware flow control. Full duplex SPI with an interrupt line is also available. The firmware loaded on the module defines the host interface and, to modify it, simply change the firmware without modifying the hardware.
