Overview
The LILYGO T-Lion (also known as T-Controller) is an ESP32-WROVER-based development board combining a 0.96-inch SSD1306 OLED display with a five-way navigation button in a narrow 108.51mm × 29.01mm profile. It carries 4MB SPI flash, 8MB PSRAM, and a dedicated 18650 battery holder with a BAT switch for portable operation. USB charging at 5V/1A through a CH9102 USB-to-TTL chip handles both programming and battery top-up. The ESP32 provides WiFi 802.11 b/g/n (up to 150Mbps) and Bluetooth 4.2 BR/EDR plus BLE for wireless connectivity. All standard ESP32 interfaces — UART, SPI, I2C, ADC, DAC, PWM, I2S — are accessible via pin headers, making it suitable for handheld sensor displays and portable IoT projects.
