# Optional hardware preparation

VB32G4 are normally ready for work straight out-of-the-box. However, let's check the configuration just in case. Connect the VB32G4 to the ST-LINK/V2 programmer and launch the STM32CubeProgrammer. Press the "**Connect**" button in the upper right corner. After successful connection go to the **OB** tab.
