Due to the advantages like ultra low power consumption, wide viewing angle, clear display without electricity, it is an ideal choice for applications such as shelf label, industrial instrument, and so on. No backlight, keeps displaying last content for a long time even when power downa low power consumption, basically power is only required for refreshing Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano. SPI interface, for connecting with other controller boards like Raspberry/Arduino/Nucleo, etc. Onboard voltage translator, compatible with 3.3V/5V MCUss with development resources and manual (examples for Raspberry Pi/Jetson Nano/Arduino/STM32) Note that you cannot use Partial refresh all the time, you should full refresh e-paper regularly, otherwise, ghost problem will get worse even damagese set the e-Paper to sleep mode or power off it directly, otherwise, the e-Paper is damaged because of working in high voltage for long time. You need to update the content of three-color e-Paper at least one time every 24h to avoid from burn-in problem.
