The image shows a close-up of a green printed circuit board (PCB) with various electronic components attached to it. On the left side of the board, there is a black circular component with a small hole in the center. Next to it, there are several smaller electronic components such as resistors, capacitors, and transistors. 

On the top right corner of the PCB, there appears to be a small orange circuit board with a black connector. On top of the green circuit board, on the bottom left corner, there seems to be an electronic component, possibly a power supply or a control panel.

Overall, the image shows the components and their connections on the PCB.
