Using this 7.5-inch ePaper display is easy. Just connect it to your device as instructed. Since it has ultra low power consumption, you can leave it unplugged without losing the image, which is great for saving energy. However, keep in mind that it takes 14 seconds to refresh, so it's best used for things that don't need frequent updates like weather stations or high - tech labels. As for maintenance, keep it away from direct heat and moisture. There's no need for complex cleaning; just use a soft, dry cloth to gently wipe the screen. Remember, this is a SparkX product. It's been tested, but there are no guarantees and no live technical support. If you have any issues or questions, head over to our forum for help.
