SEENGREAT 2.13 inch e Paper Display Module 122 x 250 Pixels Two Colour Ink Screen for Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+/4B,560ms Partial and 950ms Full Refresh SPI Interface

122 x 250 pixels, 2.13 inch e-paper e-ink display module is based on Raspberry Pi 40PIN GPIO header design, applicable to Raspberry Pi series motherboard, such as Raspberry Pi Zero/Zero W/Zero WH/2B/3B/ Supports partial refresh minimum 560ms (4-wire SPI status) and full refresh minimum 950ms (4-wire SPI status). We provide open source demo codes available for Raspberry Pi, Ardui. Mega and STM32 development boards SPI communication interface is reserved to facilitate connection to Arduino/STM32 and other control boards. SPI interface, less pin occupation. Adds a SPI line number selector switch Onboard voltage translator, which can be compatible with 3.3 V and 5 V MCUs Low power consumption. Keeps displaying last content for a long time even when power down. Basically power is only required for refreshing
