The image shows a close-up of a green printed circuit board (PCB) with various electronic components attached to it. The board is rectangular in shape and appears to be made of metal. On the left side of the board, there are several small electronic components such as resistors, capacitors, transistors, and integrated circuits. In the center, there is a small white chip with the letters "CH4" written on it, which is likely a component of the PCB. The PCB itself is rectangular and has a smooth surface.
