Waveshare 2,9-Zoll 3-Farb E-Paper-Display Module (B) 296x128

2.9 inch e-Paper Module (B) 2,9-Zoll 3-Farbe E-Paper-Display Module A compact rot, schwarz, and weiß E-Paper-Display module with 296 × 128 Auflösung, SPI-Schnittstelle, ultra-low Stromversorgung consumption, and paper-like visibility under ambient light. Key Features 2.9 inch e-paper panel with 296 × 128 Auflösung. Three-Farbe display: rot, schwarz, and weiß. No backlight requirot; content remains visible after Stromversorgung is removed. Ultra-low Stromversorgung consumption, mainly requirot during refresh. SPI-Schnittstelle for Raspberry Pi, Jetson Nano, Arduino, STM32, and other controller boards. Onboard voltage translator for 3.3V and 5V MCU compatibility. Technische Daten Betriebsspannung 3.3V / 5V Anzeigefarbe rot, schwarz, weiß Schnittstelle 3-wire SPI / 4-wire SPI grau scale 2 Auflösung 296 × 128 pixels Anzeigefläche 66.90 × 29.06mm Außenabmessungen 89.5 × 38mm Full refresh time 15s Refresh Stromversorgung 30mW typ. Standby current <0.01uA Why E-Paper E-paper uses microcapsule electrophoretic display technology, reflecting ambient light like printed paper. It has a wide viewing angle, remains readable under natural or lamplight, and does not need a backlight. SPI-Schnittstelle The onboard SPI Steuerschnittstelle supports common controller boards. Pin functions are organized below for quick integration. VCC 3.3V / 5V GND Masse DIN SPI MOSI CLK SPI SCK CS SPI chip select, active low DC Data / command selection RST External reset, active low BUSY Busy status output, active low Application Examples Suitable for price tags, shelf labels, asset or equipment tags, conference name tags, industrial instruments, and low-Stromversorgung information displays.
