LILYGO T4-S3 board combines 2.41-inch AMOLED touchscreen display with ESP32-S3R8 microcontroller

T4-S3 ESP32-S3 smart AMOLED display

LILYGO T4-S3 is yet another ESP32-S3 board with an integrated display, but the main difference here is the 2.41-inch AMOLED touchscreen display with brighter colors than typical TFT displays. It’s actually not the first ESP32-S3 board with an AMOLED display from LILYGO as we previously covered the T-Track and T-Display-S3 AMOLED boards from the company, but the new T4-S3 has a larger 2.41-inch display with touchscreen function and an aspect ratio that may make it more suitable for a wider range of HMI applications.   LILYGO T4-S3 specifications: SoC – Espressif ESP32-S3R8 CPU – Dual-core Tensilica LX7 microcontroller up to 240 MHz with vector instructions for AI acceleration Memory – 8MB PSRAM Wireless – WiFi 4 and Bluetooth 5.0 LE + Mesh connectivity Storage – 16MB SPI flash, MicroSD card socket Display – 2.41-inch RGB AMOLED touchscreen display with 600×450 resolution (QSPI controller) with 800cd/m2 brightness, 36.2 x 48.96mm active […]

LILYGO T-Track ESP32-S3 board combines 1.1-inch AMOLED display with trackball

LILYGO T-Track board

After the T-Display-S3 AMOLED board, LILYGO has launched another ESP32-S3 board with an AMOLED display named the T-Track that features a smaller 1.1-inch AMOLED display and a trackball that allows the user to navigate any menu or user interface shown on the display. The rest of the board’s specifications are very similar with an ESP32-S3R8 dual-core chip with 8MB PSRAM providing WiFi and BLE connectivity, a 16MB SPI flash for storage, two rows of pins for up to 18x GPIOs, a Qwicc connector for module expansion, and support for USB-C charging and a LiPo battery for power. T-Track specifications: Wireless MCU – Espressif Systems ESP32-S3R8 dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, 8MB PSRAM, wireless connectivity Storage – 16MB flash Connectivity via ESP32-S3 2.4 GHz 802.11 b/g/n Wi-Fi 4 with 40 MHz bandwidth support Bluetooth Low Energy (BLE) 5.0 connectivity with […]

T-Display-S3 AMOLED – An ESP32-S3 board with a 1.9-inch AMOLED Display

ESP32-S3 board with an AMOLED display

There are plenty of ESP32 series boards with display usually TFT or E-Ink, but I don’t think I’ve ever seen one with an AMOLED display and that’s what Lilygo is offering with the “T-Display-S3 AMOLED” board equipped with an ESP32-S3 WiFi and Bluetooth microcontroller and a 1.9-inch AMOLED display. The new board is almost the same as the T-Display-S3 board introduced last year, except for a display with higher resolution, more vibrant colors, and a wider viewing angle, plus a 3D antenna, and a few extra I/Os. T-Display-S3 AMOLED specifications: Wireless MCU – Espressif Systems ESP32-S3R8 dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, 8MB PSRAM, wireless connectivity Storage – 16MB flash Connectivity via ESP32-S3 2.4 GHz 802.11 b/g/n Wi-Fi 4 with 40 MHz bandwidth support Bluetooth Low Energy (BLE) 5.0 connectivity with long-range support, up to 2Mbps data rate. 3D antenna […]

Nubia Watch Comes with a 4-inch AMOLED Flexible Display (Crowdfunding)

Nubia Watch Flexible Display

We previously covered Nubia–α wearable “smartphone” in 2018. The device was basically a smartwatch with a long curved display, and at the time was at the prototype/design stage. There’s now a similar, but more refined Snapdragon Wear 2100 powered Nubia Watch with a 4.01-inch AMOLED flexible display that has recently launched on Kickstarter. It’s unclear whether it’s related to the older prototype, as the company claims to have conceptualized the watch in October 2019. Nubia Watch hardware specifications: SoC – Qualcomm Snapdragon Wear 2100 (8909Q) quad-core Cortex A7 processor with Adreno 304 GPU System Memory – 1GB RAM Storage – 8GB storage Display – 4.01-inch AMOLED flexible 2-point touchscreen display with 960 x 192 resolution covered with Schott glass Connectivity Bluetooth 4.1 GNSS – GPS, GLONASS, Beidou Sensors – Accelerometer & gyroscope, pressure sensor, heart-rate sensor, geomagnetic sensor Misc – Power button Battery – 425 mAh Lithium battery good for […]

YotaPhone 3 Dual Screen Smartphone to Launch for $360 and Up (in China)

Russia based Yota makes some unusual phones with dual display with a standard color front display, and an e-paper rear display that allows you to check the time without pressing a button, keeping displaying important information even when your battery is completely discharged, and more. The first Yotaphone was launched in December 2012, followed by a prettier and more powerful Yotaphone 2 in December 2014, but we’ve had to wait nearly three years for the company – with some fresh money and technical involvements from Chinese partners – to introduce YotaPhone 3 at the Russian Embassy in Beijing. The phone is powered by a Qualcomm Snapdragon 625 processor, and features a 5.5″ super AMOLED display on the front, and a 5.2″ E-Ink display on the back. Yotaphone 3 preliminary  (& partial) specifications: SoC – Qualcomm Snapdragon 625 octa-core Cortex A53 processor @ up to 2.0 GHz with Adreno 506 GPU System […]

Samsung Super Amoled Plus Displays

Samsung further improved their Super AMOLED technology and designed “Super AMOLED Plus” screens with the following characteristics: Easier Reading: Improved screen image (50% more sub-pixels (8 to 12)) Save Power Consumption: Real Black (i.e no energy is used to display black) Slimmer: Reduced panel depth by 14% This new technology will improve contrast and outdoor visibility. Samsung will release 2 smartphones (Samsung Infuse 4G – i997)  using that technology later this year (Q2 2011) with 4.3″ and 4.5″ screens, using 1.2 GHz single core hummingbird processor and running Android 2.3 (gingerbread).
