The &gt;170-degree viewing angle is an extra advantage, and with no backlight, e-papers reflect the ambient light incident on them, resulting in extremely low power consumption.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"576\" height=\"1024\" src=\"https:\/\/www.electronicsforu.com\/wp-contents\/uploads\/2024\/01\/E-paper-Clock-using-ESP32.webp\" alt=\"DIY E-paper Clock using ESP32\" class=\"wp-image-133080\" style=\"width:377px;height:auto\" srcset=\"https:\/\/www.electronicsforu.com\/wp-contents\/uploads\/2024\/01\/E-paper-Clock-using-ESP32.webp 576w, https:\/\/www.electronicsforu.com\/wp-contents\/uploads\/2024\/01\/E-paper-Clock-using-ESP32-281x500.webp 281w\" sizes=\"auto, (max-width: 576px) 100vw, 576px\" \/><figcaption class=\"wp-element-caption\">Fig. 1: E-paper Clock using ESP32<\/figcaption><\/figure><\/div>\n\n\n<p>However, one significant drawback of the e-paper is its slow refresh rate, ranging from 3 to 8 seconds. This is the main reason why e-papers have not yet entered the mobile screen arena; they are mostly limited to e-readers and clock displays, which feature only hour and minute displays. Fig. 1 displays the E-paper clock project&#8217;s prototype. <\/p>\n\n\n\n<p>The components (bill of materials) used in this E-paper clock are listed below.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td colspan=\"3\"><strong>Bill of Materials<\/strong><\/td><\/tr><tr><td><strong>Items<\/strong><\/td><td><strong>Quantity<\/strong><\/td><td><strong>Description<\/strong><\/td><\/tr><tr><td>ESP32 \u2013 MCU (MOD1)<\/td><td>1<\/td><td>Microcontroller<\/td><\/tr><tr><td>3.3V voltage<br>regulator (IC1)<\/td><td>1<\/td><td>HT7333A regulator<\/td><\/tr><tr><td>19cm (7.5-inch) black- and-white e-paper (MOD2)<\/td><td>1<\/td><td>Display<\/td><\/tr><tr><td>Wires, PCB, connector<\/td><td><br><\/td><td><br><\/td><\/tr><tr><td>10\u00b5F, 16V electrolytic capacitors (C1, C2)<\/td><td>2<\/td><td><br><\/td><\/tr><tr><td>RTC module (MOD3)<\/td><td>1<\/td><td><a href=\"https:\/\/www.analog.com\/media\/en\/technical-documentation\/data-sheets\/ds3231.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">DS3231<\/a><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>E-paper Clock Circuit<\/strong><\/h2>\n\n\n\n<p>Fig. 2 illustrates the circuit diagram of the E-paper clock.
