Feature

●?This product is an E-paper device adopting the image display technology of Microencapsulated Electrophoretic Display, MED.
●?Under ambient light, the E-paper screen still has high visibility with a wide viewing angle of 180 degrees.
●?The initial approach is to create tiny spheres, in which the charged color pigments are suspended in the transparent oil and would move depending on the electronic charge.
●?The E-paper screen display patterns by reflecting the ambient light, so it has no background light requirement.
●?SPI interface, for connecting with controller boards like RPi/Jetson Nano/Arduino/STM32, etc.Comes with development resources and manual(driver board schematic, examples for RPi/Arduino/STM32).
