7.5 Inch E-Paper Show Hat (B) is an E-Ink show HAT for Raspberry Pi, 7.5inch, 800 *480 decision, with embedded controller, and is well communicable through SPI interface. This system helps pink, black, and white three-colour show. As a consequence of the advantages like ultra-low energy consumption, extensive viewing angle, clear show with out electrical energy, it is an ideal alternative for purposes like shelf label, industrial instrument, and so forth. It has a full refresh time of 16seconds. Included with Refresh energy: 38mW(sort.) and Standby energy: 170°. This system is included with handbook assets and growth assets. It helps On-board voltage translator, appropriate with 3.3V/5V MCUs and has a dot pitch of 0.205 x 0.204.
E-paper show makes use of microcapsule electrophoretic know-how for displaying, the precept is: charged particles suspended inside the clear fluid will transfer to sides of microcapsule when {an electrical} area is utilized, making the microcapsule seem by reflecting ambient gentle, at the same time as conventional printed paper.
E-paper show will clearly show photos/texts underneath lamplight or pure gentle requires no backlight and options almost as much as 180° viewing angle. It’s normally used as e-reader because of its paper-like impact.
This product is an E-paper system adopting the picture show know-how of Microencapsulated Electrophoretic Show, MED. The preliminary method is to make tiny spheres, throughout which the charged color pigments are suspending inside the clear oil and would transfer relying on the digital cost. The E-paper display show patterns by reflecting the ambient gentle, so it is no background gentle requirement. Below ambient gentle, the E-paper display nonetheless has excessive visibility with a large viewing angle of 180 levels. It’s the perfect alternative for E-reading. (Be aware that the e-Paper can not help updating instantly underneath daylight).Completely different from the normal SPI protocol, the info line from the slave to the grasp is hidden for the reason that system solely has show requirement.
