Note: Please avoid long-time high-frequency refresh when using the device. The recommended refresh interval is every 15 seconds. Do not expose to ultraviolet rays for an extended period to prevent irreversible damage to the ink screen. The low-power management solution of CoreInk differs from that of CORE and StickC devices. The PWR button serves as a power-on button (long press 2s). To shut down the device, use the software API or press the reset button on the back.
