This is a very clean PCB with a large number of passive components, some diodes, and 14 transistors mounted on the component side of the single layer board. There are five quality control stamps on the solder side, and component IDs, the manufacturer's name, and the module purpose on the component side. This object is remarkably clean, with no signs of damage.
