The TTGO T-Display ESP32 (AM-009) is a high-performance development board that combines the powerful ESP32 microcontroller with a vibrant 1.14-inch color LCD. It is a preferred choice for 2026 IoT projects requiring a compact visual interface and high-speed wireless connectivity.
Long Description
The AM-009 TTGO T-Display is an all-in-one IoT solution designed for developers who need more than just a standard microcontroller. Powered by the dual-core ESP32-D0WDQ6-V3, it offers integrated Wi-Fi and Bluetooth (Classic and BLE) capabilities. The standout feature is the onboard 1.14-inch IPS LCD display, driven by the ST7789 controller, which provides crisp 135×240 resolution for real-time data visualization, status icons, or user menus.
Its compact form factor includes a USB Type-C interface for modern connectivity and an integrated battery charging circuit (JST-GH connector), making it ideal for portable, battery-powered devices. Whether you are building a smart home controller, a portable weather station, or a wearable diagnostic tool, the T-Display provides the processing power and visual feedback necessary for professional-grade prototyping.
Key Features
  • Integrated Color Display: 1.14-inch IPS LCD offers vivid colors and wide viewing angles for data monitoring.
  • Powerful Dual-Core Processor: The ESP32 chip operates at up to 240MHz, handling complex tasks and wireless stacks simultaneously.
  • Dual-Mode Wireless: Supports 802.11 b/g/n Wi-Fi and Bluetooth v4.2 (BR/EDR/BLE).
  • Modern USB-C Interface: Simplifies programming and power delivery while ensuring compatibility with modern cables.
  • Portable Power Ready: Includes a 2-pin JST connector and an integrated Li-Po battery management system.
  • User Interactivity: Features two programmable onboard buttons for menu navigation or user input.
Usage Instructions
  1. Programming Environment: Compatible with Arduino IDE, PlatformIO, MicroPython, and CircuitPython. Install the “ESP32” board manager in your IDE to begin.
  2. Display Library: For best results, use the TFT_eSPI library. You must configure the library’s User_Setup.h file to match the ST7789 driver and the specific pinout of the T-Display (refer to our online documentation for the pin map).
  3. Battery Operation: Connect a 3.7V Li-Po battery to the JST port. The board will charge the battery automatically when plugged into USB-C.
  4. Flashing Code: Press and hold the “Boot” button if the board fails to enter download mode automatically during programming.
  5. GPIO Access: The side headers are breadboard-friendly, allowing you to connect external sensors to the available GPIOs.
Q: Can this board run on battery power and USB simultaneously?

Yes. The onboard power management IC handles “Power Path” management, allowing it to run the board while charging the connected battery.

Q: What is the maximum battery size supported?

There is no software limit to the capacity (mAh), but the charging current is typically set to 500mA. Ensure your battery is a 3.7V Lithium-Polymer type with a compatible JST-GH 1.25mm connector.

Q: Is the display touch-sensitive?

No, the 1.14″ LCD is a non-touch display. Navigation is typically handled via the two onboard programmable buttons or external sensors.

Q: Why is my display blank after uploading code?

Ensure you have defined the correct pins for the ST7789 driver. In the TFT_eSPI library, you must select the correct setup file for “TTGO T-Display.” Also, ensure the backlight pin (GPIO 4) is set to HIGH in your code.

Q: Do you provide volume discounts for educational or corporate buyers?

Yes. For bulk orders or B2B purchasing, please contact our sales department. We offer tiered pricing and technical support packages for large-scale deployments in STEM and industrial IoT.
