P-NUCLEO-WB55 is the STM32 Nucleo evaluation kit for communication within the Bluetooth 5.0 and IEEE 802.15.4-2011 protocols. The kit includes a USB Dongle device that allows you to use a PC for testing purposes and a Nucleo development board with an STM32WB microcontroller. The package allows you to implement the Bluetooth 5.0 protocol in your projects without the need for additional devices.
The STM32WB series is based on an ARM® Cortex®-M4 core running at 64 MHz (application processor) and an ARM® Cortex®-M0 + core running at 32 MHz (network processor). Thanks to these two completely independent cores, this innovative architecture is optimized for real-time application (processing of software related to radio) as well as flexible use of resources and energy management.
USB Dongle MB1293C
The device is based on the STM32WB (STM32WB55CGU6U) microcontroller in the UFQFPN48 package. In addition, the device has a USB Type A connector that can be used to connect the set to a computer. Likewise USB Dongle operates in the 2.4GHz band and provides support for Bluetooth® specification v5.0 and IEEE 802.15.4-2011 (PHY and MAC layer).
The USB Dongle has an overall dimensions of 50.53mm in length and 26.12mm in width. So it is a handy USB sender that can be successfully used, for example, when developing applications. Of course, wireless communication takes place through a built-in PCB antenna or an external antenna (UFL connector)
The USB Dongle board has three LEDs in red, green and blue. In addition, the user has a button and expansion connectors (20 pins of castellated holes). In addition, the user has at his disposal the SW2 switch, which is used to put the STM32WB microcontroller into the bootloader mode. Changing the position of the switch to BOOT0 activates the mode.
Nucleo-68 Board MB1355C
The board is equipped with two types of connectors: Arduino Uno V3 and ST morpho (all GPIO pins of the microcontroller) provide access to each of the microcontroller components.
The nucleo board has peripheral component. Thus, there are three red, green and blue LEDs on the board. Three buttons labeled as SW1, SW2 and SW3. Of course, the board include STLINK / V2-1 programmer (avilable via microUSB connector called as ST-LINK – CN15 on board). Port microUSB marked as CN1 is for user purposes.
PCB antenna is avilable on the board. Optionally, you can install an SMA socket (not included) and connect an external antenna. Nucleo board can be powereb by ST-LINK port. Of course, another option to supply the board is use external power supply source. As standard, the Nucleo board has virtual COM ports available through the ST-LINK connector.
