AirTab 15.6″ Portable Display Provides 2x USB-C Inputs (Crowdfunding)

While portable displays have been available as far back as at least 2012, they’ve become more popular in recent years as they can both offer a secondary display to your laptop, or add a larger screen to your smartphone. In the last two years, we’ve already covered BlitzWolf BW-PCM1, T-bao T15A, TAIHE Gemini (which ended up being a failure), Airview, and Desklab among others. But apparently, there’s room for more with the launch of AirTab, a 15.6″ portable touchscreen or non-touch monitor, on Kickstarter that’s already surpassed its $10,000 funding target. AirTab specifications: 15.6″ display with 1920×1080 resolution up to 60 Hz refresh rate; 4ms response time; 256 cd/m2 brightness Touchscreen – Air Touch model only USB – 2x USB-C ports Power Supply – Dimensions – 335 x 245 x 4.9 mm Weight – 500 grams AirTab comes with a foldable magnetic cover that allows the display to be used […]

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 […]
