This is an E-Ink display module, 1.54inch, 200x200 resolution, with embedded controller, communicating via SPI interface, supports partial refresh.
Due to the benefits like ultra low power consumption, wide viewing angle, great effect under sunlight, it's a perfect choice for applications like shelf label, industrial instrument, and so on.
The 1.54inch e-Paper is updated to 1.54inch e-Paper V2 version. Codes of the two version are not compatible with each other. Except for the controller and codes, the new V2 version is exactly the same as the old one. If you're users of the old version, you would like to update your codes also for your new order.
This product is an E-paper device adopting the image display technology of Microencapsulated Electrophoretic Display, MED. The initial approach is to make tiny spheres, during which the charged color pigments are suspending within the transparent oil and would move counting on the electronic charge. The E-paper screen display patterns by reflecting the ambient light, so it's no background light requirement. Under ambient light, the E-paper screen still has high visibility with a wide viewing angle of 180 degrees. It is the ideal choice for E-reading. (Note that the e-Paper cannot support updating directly under sunlight) reflecting the ambient light, so it has no background light requirement. (Note that the e-Paper cannot support updating directly under sunlight)
Different from the traditional SPI protocol, the data line from the slave to the master is hidden since the device only has a display requirement.
It requires no No backlight, keeps displaying last content for a long time even when power down and supports red, black, and white three-color display.
It supports SPI interface, for connecting with controller boards like Raspberry Pi/Nucleo, etc and has an operating voltage of3.3V. It comes with development resources and manual (examples for Raspberry Pi/STM32).
