296x128 2.9inch E-Ink Raw Black / White e-Paper Display

This is a black/white E-Ink/E-Paper raw panel display module without a board. The ePaper display has a 2.9inch diagonal with a resolution of 296x128 pixels. Thanks to the integrated controller, you can control the display via the SPI interface. This black/white display supports partial area updates. Thus, individual areas can be updated quickly within 0.3 seconds. Updating the entire display also only takes 2 seconds. Due to the low power consumption, it is great for battery-powered applications. These displays are also used in retail as price tags, where they can run on a single battery for several years. The display has a very good viewing angle and can also be read very well in sunlight. This low-cost display is perfect for connecting to the "ESP8266 Universal Raw e-Paper Driver Board WiFi" board.
