E-paper display will clearly display images/texts under lamplight or natural light, requires no backlight, and features nearly up to 180° viewing angle. It is usually used as e-reader due to its paper-like effect. Standard Raspberry Pi 40PIN GPIO header compatible with Raspberry Pi series boards, Jetson Nano Raspberry Pi in the photo are NOT included. Onboard SPI control interface for use with other controller boards like STM32/Arduino VCC 3.3V/5V GND Ground DIN SPI MOSI pin CLK SPI SCK pin CS SPI chip selection, low active DC Data / Command selection (high for data, low for command) RST External reset, low active BUSY Busy status output, high active Onboard voltage translator compatible with 3.3V / 5V MCUs Application examples Suitable for price Tags, asset/equipment Tags, shelf labels, conference name tags...
