It supports 3-wire\/4-wire SPI switching and is compatible with various main controller development requirements.\u003c\/p\u003e\n\u003cp\u003e[Product Features]\u003c\/p\u003e\n\u003cp\u003e1. Four-color information display: 2.9-inch, 128(H) × 296(V) pixel display, supporting black, white, yellow, and red images, making it convenient to distinguish different types of display information.\u003cbr\u003e2. Clear ambient-light reading: Reflective, backlight-free e-paper features high contrast and a wide viewing angle, suitable for viewing content under ambient light.\u003cbr\u003e3. Fast content updates: At 25°C, the panel fast refresh time is approximately 11 seconds, suitable for periodically updating status and information.\u003cbr\u003e4. Low-power content retention: The module supports sleep mode; the bistable display of e-paper can reduce power consumption while maintaining static content.\u003cbr\u003e5. Multiple connection methods: The module provides flexible main controller connection options, suitable for the wiring requirements of different embedded projects.\u003cbr\u003e6. Onboard signal adaptation: An integrated level-shifting buffer provides adaptation for signal connections between the module and the main controller.\u003cbr\u003e7. Flexible SPI configuration: Supports 3-wire\/4-wire SPI switching, allowing the connection method to be selected according to the main controller communication requirements.\u003cbr\u003e8. Onboard level-shifting chip, compatible with 3.3V and 5V microcontroller interfaces.\u003c\/p\u003e\n\u003cp\u003e[Application Scenarios]\u003c\/p\u003e\n\u003cp\u003e1. Electronic price tags and shelf information boards: Used to display low-frequency update content such as prices, product information, inventory status, or asset identification.\u003cbr\u003e2. IoT device information terminals: Works with Arduino, ESP32, ESP32-S3, or Raspberry Pi to display sensor data and device operating status.\u003cbr\u003e3. Embedded development learning: Used for learning and prototype verification of e-paper driving, SPI communication, and display programs.\u003c\/p\u003e\n\u003cp\u003e[Specifications]  \u003cbr\u003e• Compatible main controllers: Arduino, ESP32\/ESP32-S3, Raspberry Pi  \u003cbr\u003e• Communication method: 3-wire\/4-wire SPI  \u003cbr\u003e• Panel fast refresh time: Approximately 11 seconds (25°C)  \u003cbr\u003e• Sleep mode: Supported  \u003cbr\u003e• Screen size: 2.9 inches  \u003cbr\u003e• Display resolution: 128(H) × 296(V) pixels  \u003cbr\u003e• Display colors: Black, white, yellow, red  \u003cbr\u003e• Panel display characteristics: Reflective, high contrast, wide viewing angle, bistable, no backlight required  \u003cbr\u003e• Driver chip: JD79661  \u003cbr\u003e• Product dimensions: 9.05cm*3.8cm  \u003cbr\u003e• Product weight: 0.061kg (including packaging)  \u003cbr\u003e• Package dimensions: 13*8*2.5cm\u003c\/p\u003e\n\u003cp\u003e[Learning Resources]  \u003cbr\u003eOnline tutorials are provided, including comprehensive guidance on programming implementation and image processing.\u003c\/p\u003e\n\u003cp\u003e[Package Contents]  \u003cbr\u003e2.9inch E-paper Module ×1  \u003cbr\u003eMX1.25 8PIN connection cable x1  \u003cbr\u003eScrewdriver ×1  \u003cbr\u003eScrew kit set ×1  \u003cbr\u003e8PIN pin header ×1\u003c\/p\u003e","brand":"LAFVIN","offers":[{"title":"Default Title","offer_id":48430951268540,"sku":"LB017","price":16.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0604\/9388\/9724\/files\/LB017_1-1.jpg?v=1791625098","url":"https:\/\/lafvintech.com\/products\/2-9inch-e-paper-module-four-color-electronic-paper-display-spi-e-paper-screen-with-ultra-low-power-wide-viewing-angle-for-arduino","provider":"LAFVIN","version":"1.0","type":"link"}
