Overview
The LILYGO T-Keyboard S3 Pro is a feature-rich programmable keyboard development platform based on the ESP32-S3R8 dual-core microcontroller. It integrates four 0.85-inch GC9107 TFT LCD displays (128×128 resolution each), 14 programmable WS2812 RGB LEDs, a rotary encoder, and magnetic quick-connect ports for modular expansion. A secondary STM32G030F6P6 co-processor handles low-level I/O tasks. The board supports daisy-chaining up to 6 units in a 2×3 grid via I2C communication expansion. With 16MB Flash, 8MB PSRAM, Wi-Fi, and Bluetooth 5, it is suited for custom macro keyboards, multi-display control panels, and programmable HMI systems. Both a primary unit and slave keyboard variant are available for building larger keyboard arrays.
