Product overview
Description
The X-NUCLEO-WBA25A1 ARDUINO® interface board provides Bluetooth® LE connectivity for developer applications and can be plugged into an STM32 Nucleo board, such as NUCLEO-U385RG-Q, using the ARDUINO® Uno V3 connectors.
The ARDUINO® interface board features the Bluetooth® v6.0-compliant and FCC-certified STM32WBA25CE SoC. This device manages the complete Bluetooth® LE stack and protocols using its Arm® Cortex®-M33 core and programmable flash memory.
X-NUCLEO-WBA25A1 uses the universal asynchronous receiver transmitter (UART) interface to communicate with the STM32 Nucleo board. It supports operations with or without hardware flow control. A full-duplex serial peripheral interface (SPI) with an interrupt line is also available. The firmware loaded on the module determines the host interface. To change the interface, update the firmware without modifying the hardware.
