4.2″ and 7.5″ NFC-powered e-Paper Displays Work without Battery

e-Paper displays have great readability under sunlight, and only consume power when updated. But their refresh rate is limited, and most displays are fairly expensive. One way to reduce the cost is to completely remove the battery from the display, and update it through NFC providing both data and power. I’ve just found out about that possibility through 4.2″ and 7.5″ displays offered by Waveshare. All you need is a compatible NFC smartphone, or the company’s ST25R3911B NFC Board to power the display and transfer your image of choice. This works best for signs you may need to infrequently update such as menus, daily schedules, conference badges, labels, etc… Waveshare NFC-powered e-Paper display key features and specifications: Screens 7.5″ display 800×480 resolution 2-level greyscale 170° viewing angle Refresh Time – 5s + data transfer time 4.2″ display 400×300 resolution 2-level greyscale 170° viewing angle Refresh Time – 4s + data […]

ESP32-S2-Kaluga-1 “Multimedia” Development Board Comes with Touchscreen Display & Camera

ESP32-S2 secure WiFi processor based on Xtensa LX7 core was first unveiled in May 2019, before the datasheet was released, and the first development boards were showcased in September. The Coronavirus outbreak slowed down progress, but the company has now announced the start of mass production for ESP32-S2 SoC, ESP32-S2-WROVER & ESP32-S2-WROOM modules, and ESP32-S2-Saola-1 development board. So that means we should soon be able to buy any of those. Apart from improved security, ESP32-S2 chip also provides a USB OTG interface and interfaces for HMI (Human Machine Interface) solutions thanks to LCD & camera interfaces. So that’s probably why the company has developed ESP-S2 Kaluga-1 board with an LCD touchscreen display, touch panel, support for camera image acquisition, audio playback, and more. We do not have the full specifications at this stage, but here are some of the highlights of the board: LCD interfaces – SPI interface or 8-/16-/24-bit […]

10.3″ E-paper HDMI Display Connects to Raspberry Pi & Jetson Nano SBC’s, Computers

E-paper displays only consume power when updated, work great in bright light, and are easier on eyes when reading text. The downside is the low refresh rate which makes those impractical for videos and games, and most E-paper displays are black and white or with just a few colors. Another hindrance is that most are connected via flat cables for specific display interfaces which may not be the easiest to handle, and you may not be able to easily move the display across platforms if you wish too. Waveshare EINK-DISP-103 10.3″ E-paper display solves this little problem since it should work with any SBC or computer with an HDMI output. EINK-DISP-103 Key features & specifications: 10.1″ e-Paper display, 1872×1404 resolution (225DPI), grayscale (16 shades) Video Input – Mini HDMI port Misc – UPD/RUN switch, contrast adjustment, power indicator, screen refresh button, mode switch button Power Supply – 5V/3A recommended and […]
