The image shows a close-up of a green printed circuit board (PCB) with various electronic components. On the left side of the board, there are several resistors, capacitors, and transistors arranged in a grid-like pattern. In the center, there is a black rectangular component with the word "UMEC" written on it in white letters. The component appears to be a microcontroller, as indicated by the logo on the bottom right corner of the image. The board also has a barcode on the top left corner.
