UV erasers are tools that are used to erase or erase certain types of programmable devices, such as EPROMs or EEPROMs. These devices are programmed using ultraviolet (UV) light, and can be erased by exposing them to a high intensity UV light source, such as a UV eraser. UV erasers typically consist of a UV light source, such as a UV lamp or a UV LED, and a mechanism for exposing the device to the UV light, such as a slot or a window. They are often used in conjunction with development boards, kits, and programmers, which are used to program and test these types of devices. UV erasers are an important tool for anyone working with programmable devices, as they allow the devices to be easily reprogrammed or erased as needed.
