One of the feature that we were looking for was low power consumption. Mini Ultra 8 MHz was designed to fill this void. We also came out with an <a href=\"https:\/\/github.com\/rocketscream\/Low-Power\" target=\"_blank\" rel=\"noopener noreferrer\">Arduino compatible low power library<\/a> to allow flexible low power management of the board. If your next project needs to run on battery or without main power, this is the board you might want to consider!
