T-Display-Keyboard get it now

Overview

LILYGO T-Display-Keyboard is a handheld ESP32 development kit that combines the T-Display board (1.14-inch ST7789V IPS TFT, 240 × 135 px) with a compact physical keyboard shell. Based on the ESP32 dual-core LX6 processor at up to 240 MHz, it provides Wi-Fi 802.11 b/g/n and Bluetooth 4.2 + BLE. The keyboard shell exposes a full QWERTY-style keypad and a battery holder for portable, standalone applications. It is ideal for handheld controllers, message terminals, remote interfaces, and educational embedded projects.
