ESP32-S3 Touch AMOLED 1.91

Waveshare has launched an ESP32-S3 1.91-inch AMOLED development board with a 6-axis motion sensor designed for the rapid prototyping of IoT and portable projects with interactive displays. The board is built around the ESP32-S3R8 chip, featuring a 32-bit LX7 dual-core processor running at up to 240MHz, with integrated 2.4GHz Wi-Fi and Bluetooth BLE 5. It also includes 16MB Flash, 8MB PSRAM, 512KB SRAM, and 384KB ROM for efficient processing and memory management. At the core of its display capabilities is a 1.91-inch AMOLED screen with a 240×536 resolution, supporting 16.7 million colors. Powered by the RM67162 controller and connected via the QSPI interface, the display is ideal for running GUI applications like LVGL. The board is available in both touch and non-touch versions, with the touch-enabled models using the FT3168 touch IC. Other features include a QMI8658 6-axis IMU, a microSD card slot, and a Lithium battery header. The ESP32-S3 […]

T-Display-S3-AMOLED-1.43 – A 1.43-inch round AMOLED touchscreen display with an ESP32-S3 wireless MCU

T-Display-S3-AMOLED-1.43

We’ve already seen a few ESP32-S3 boards with an AMOLED display and plenty with round displays such as SB Components’ Dual Roundy, LILYGO T-RGB ESP32-S3, MaTouch ESP32-S3 Rotary IPS display among others, but I had yet to see an ESP32-S3 board with a round AMOLED display. That’s just what the LILYGO T-Display-S3-AMOLED-1.43 has to offer. The ESP32-S3 board features a 1.43-inch round AMOLED with 466×466 resolution and a capacitive touchscreen, a microSD card slot for storage, an RTC with backup battery, two 14-pin headers and a Qwiic UART connector for expansion, a USB-C port for power/charging and programming, and a 2-pin connector for a LiPo battery. T-Display-S3 AMOLED-1.43 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 […]

ESP32-S3 rotary encoder features 1.2-inch AMOLED touchscreen display and Qwiic connectors

LILYGO T-Encoder Pro

LILYGO T-Encoder-Pro is a rotary encoder based on Espressif Systems ESP32-S3 WiFi and Bluetooth SoC, equipped with a 1.2-inch AMOLED with touchscreen support, and two Qwiic connectors for expansion. LILIGO T-Encoder was introduced in 2022 with ESP32 WiFi and Bluetooth SoC and a few GPIOs that enabled it to be fitted on a 2-key keypad shield. The LILYGO T-Encoder Pro has a completely different design with a more advanced ESP32-S3 SoC, an integrated touchscreen display, and GPIOs are now exposed through Qwiic connectors instead of headers. LILYGO T-Encoder-Pro specifications: Wireless SoC – Espressif Systems ESP32-S3R8 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration Memory – 512KB RAM, 8MB PSRAM Wireless – 2.4 GHz WiFi 4 and Bluetooth Storage – 16 MB flash (W25Q128) Display – 1.2-inch rounded AMOLED with ∅390mm resolution via SH8601A-W14-T06 QSPI controllers; CHSC5816 I2C touch and rotary encoder chip […]

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 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 […]

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 […]
