Introduction
The LILYGO T-Deck Plus is a feature-rich, portable embedded development kit powered by the high-performance ESP32-S3 chip. It integrates a 320x240 resolution ST7789 LCD display, an SX1262 LoRa long-range communication module, an ES7210 audio codec, a microphone, a speaker, and TF card storage expansion.
Its hardware configuration includes optional components such as a trackball, a mechanical keyboard (available in black or white), a 1/4-inch nut mounting interface, and support for GPS positioning and 2000mAh battery power. It also features voltage detection for optimized power management.
The board connects various modules via SPI and I2C interfaces (such as LoRa, LCD, and touch control), and provides an AUX antenna extension interface. It is well-suited for IoT terminals, remote control systems, audio interaction, and outdoor mobile development scenarios.
