T-Display-S3-Long board features ESP32-S3 WiSoC, a wide touchscreen display

LILYGO has designed plenty of ESP32 boards with an integrated display, but the new T-Display-S3-Long may be suitable for different applications since the ESP32-S3 board comes with a wide 3.4-inch touchscreen display with 640×180 resolution.

The WiFi and Bluetooth wireless display board is powered by an ESP32-S3R8 WiSoC with 8MB PSRAM, and comes with a 16MB SPI flash, two Qwiic connectors and a 30-pin header for expansion, a USB Type-C port for power, charging, and programming, and a 2-pin connector for an optional LiPo battery.

ESP32-S3 board wide touchscreen displayLILYGO provides PlatformIO/Arduino firmware and samples (factory test code, TFT sample, touchscreen sample, and LVGL demo), PDF schematics, datasheets, and basic documentation on GitHub. Since documentation is limited, and there aren’t any full-functioning projects, the T-Display-S3-Long is mostly suitable for people with Arduino/PlatformIO programming experience and most beginners will probably struggle with the board…

LILYGO is taking pre-orders for the T-Display-S3-Long ESP32-S3 wide display board on Aliexpress for $33.98 including shipping with deliveries scheduled to start by mid-December. Since Aliexpress’ Black Friday sales are not quite over yet, you should be able to use codes such as USAFF6 (US only) or CNXALI6 (most of the world with some exceptions) to get a $6 discount for orders over $45.

i hope that expressif doesn’t take to long making more risc-v based chips. The ESP32-S3 with 1 or 2 risc-v cores and adding bluetooth le 5.2 or newer instead of 5.0 would make this microcontroller very tasty.
