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 area
- USB – USB Type-C port for power and programming
- Antenna – 3D antenna, IPEX antenna connector
- Expansion
- 2x STEMMA QT/Qwiic I2C/UART connectors
- 30-pin 1.27 pitch header with GPIOs. I2C, UART, 3.3V, BAT, GND
- Misc – BOOT and Reset buttons, battery switch
- Power Supply
- 5V via USB Type-C port
- 1.25mm pitch JST connector for LiPo battery, battery level detection
- Power Consumption
- Sleep – About 160uA
- WiFi on – 90 to 230 mA
- Dimensions – 56 x 44 x 13 mm
The company claims the T4-S3 devkit supports Arduino, PlatformIO IDE, and MicroPython, but only provides Arduino/PlatformIO sample code on GitHub with the factory test code, a Qwicc GPS (UART) sample, a Qwiic HP303B I2S sensor sample, a touchpad demo, a TFT-eSPI sprite sample, and various LVGL samples. There are also other samples such as a LumenMeter, a PMU voltage detection sample, and a PMU interrupt sample that are designed for the T-Display-AMOLED-Lite board with a 1.47-inch AMOLED only. The GitHub repository also includes datasheets, mechanical drawings, firmware files, and PDF schematics.
LILYGO is selling the T4-S3 ESP32-S3 2.14 AMOLED board for $65.98 including shipping on Aliexpress.
