| The table {{ref>sutavrlabtable1}} lists all hardware components and details. Note that some elements are accessible, but their use is not supported via the remote lab, e.g., buttons and a buzzer.\\ The node is depicted in the figure {{ref>sutavrlabimage1}}. | The table {{ref>sutavrlabtable1}} lists all hardware components and details. Note that some elements are accessible, but their use is not supported via the remote lab, e.g., buttons and a buzzer.\\ The node is depicted in the figure {{ref>sutavrlabimage1}} and its interface visual schematic is presented in the figure {{ref>sutavrlabimage1_2}}. The schematic presents only components used in scenarios and accessible via the VREL NextGen environment (controllable and observable via video stream), omitting unused components such as buttons, a buzzer, and a potentiometer. |
