Waveshare 2.13 inch 212x104 Pixel Flexible E-Paper E-Ink Raw Display Panel 212x104, 2.13inch flexible E-Ink raw display, blackwhite dual-color, SPI interface, without PCB Overview 1. This is a flexible E-Ink raw display, 2.13inch, 212x104 resolution, with embedded controller, communicating via SPI interface, supports partial refresh. 2. Compared with normal e-Paper panels, this flexible panel allows bending without being damaged, and it's thinner and lighter. 3. Combined with the advantages like ultra low power consumption, wide viewing angle, clear display without electricity, it is an ideal choice for applications where curved surface display is required, such as industrial instruments, smart wearable-devices, and so on. Features 1. Flexible e-Paper, the display section is bendable (DON'T bend the FPC section) 2. No backlight, keeps displaying last content for a long time even when power down 3. Ultra low power consumption, basically power is only required for refreshing 4. Comes with development resources and manual (driver board schematic, examples for Raspberry PiArduinoSTM32) Specifications 1. Operating voltage: 3.3V 2. Interface: 3-wire SPI, 4-wire SPI 3.
