No backlight required, power off can keep the last screen display for a long time
Very low power consumption, basically only consumes power when refreshing
Based on Raspberry Pi standard interface design, compatible and can be directly inserted into Raspberry Pi 2 generation B/3 generation B/Zero/Zero W
SPI control interface, can access Raspberry / Arduino / Nucleo and other main control boards
Provide a complete supporting information manual (sample programs such as Raspberry/Arduino/STM32)
