Description

The NUCLEO-WB55RG and NUCLEO-WB15CC STM32WB Nucleo-64 boards are

Bluetooth® Low Energy (BLE) wireless and ultra-low-power devices embedding a

powerful and ultra-low-power radio compliant with the Bluetooth® Low Energy (BLE)

SIG specification v5.2.

NUCLEO-WB55RG also offers a radio compliant with IEEE 802.15.4-2011 standard

and allows the simple and quick evaluation of STM32WB55xx and STM32WB35xx

devices.

The ARDUINO® Uno V3 connectivity support and the ST morpho headers provide

an easy means of expanding the functionality of the STM32WB Nucleo open

development platform with a wide choice of specialized shields.
