7.5Inch E-Paper Show Hat (C) is an E-Ink show HAT for Raspberry Pi, 7.5inch, 640 *384 decision, with embedded controller, and is communicabe through SPI interface. It helps purple, black, and white three-colour show. As a result of advantages like ultra-low energy consumption, broad viewing angle, clear show with out electrical energy, it is an ideal selection for functions like shelf label, industrial instrument, and so forth. It has a full refresh time of 16seconds. Integrated with Refresh energy: 38mW(kind.) and Standby energy: 170°. This system is integrated with handbook assets and growth assets. It helps Onboard voltage translator, suitable with 3.3V/5V MCUs and has a dot pitch of 0.255 x 0.255.
E-paper show makes use of microcapsule electrophoretic know-how for displaying, the precept is: charged particles suspended throughout the clear fluid will transfer to sides of microcapsule when {an electrical} area is utilized, making the microcapsule seem by reflecting ambient mild, whilst conventional printed paper.
E-paper show will clearly show photographs/texts beneath lamplight or pure mild requires no backlight and options practically as much as 180° viewing angle. It’s often used as e-reader due to its paper-like impact.
This product is an E-paper system adopting the picture show know-how of Microencapsulated Electrophoretic Show, MED. The preliminary strategy is to make tiny spheres, throughout which the charged coloration pigments are suspending throughout the clear oil and would transfer relying on the digital cost. The E-paper display show patterns by reflecting the ambient mild, so it is no background mild requirement. Beneath ambient mild, the E-paper display nonetheless has excessive visibility with a large viewing angle of 180 levels. It’s the perfect selection for E-reading. (Word that the e-Paper can’t help updating instantly beneath daylight).Completely different from the standard SPI protocol, the info line from the slave to the grasp is hidden because the system solely has show requirement.
