400x300, 4.2inch E-Ink display module, SPI interfaceOverviewThis is an E-Ink display module, 4.2inch, 400x300 resolution, with embedded controller, communicating via SPI interface.
Due to the advantages like ultra low power consumption, wide viewing angle, great effect under sunlight, it is an ideal choice for applications such as shelf label, industrial instrument, and so on.
FeaturesNo backlight, keeps displaying last content for a long time even when power downUltra low power consumption, basically power is only required for refreshingSPI interface, for connecting with controller boards like Raspberry Pi/Arduino/Nucleo, etc.Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32) SpecificationsOperating voltage: 3.3VInterface: 3-wire SPI, 4-wire SPIOutline dimension: 90.1mm × 77.0mm × 1.18mmDisplay size: 84.8mm × 63.6mmDot pitch: 0.212 × 0.212Resolution: 400 × 300Display color: black, whiteGrey level: 2Refresh power: 26.4mW(typ.)Standby power: <0.017mWViewing angle: >170° InterfaceSYMBOLDESCRIPTION VCC3.3V GNDGround DINSPI MOSI pin CLKSPI SCK pin CSSPI chip selection, low active DCData/Command selection (high for data, low for command) RSTExternal reset, low active BUSYBusy status output, low active
