Frequently Asked Questions

What development frameworks are supported for programming the LilyGO T-RGB board?

The board is fully compatible with the Arduino IDE using the ESP32-S3 board package, Espressif's official ESP-IDF for advanced control, and MicroPython for rapid scripting. You must configure your environment to target the ESP32-S3 chip and may need to install specific libraries for the ST7701S display driver and touch controller to utilize the round screen.

How do I connect and power the T-RGB board for a standalone project?

Power the board via its designated 5V and GND pins, typically using the provided JST connector or a USB-C cable connected to a 5V source. For battery operation, a 3.7V LiPo can be connected to the appropriate pins, leveraging the ESP32-S3's low-power sleep modes. Ensure your power supply can provide sufficient current for the display and wireless radio during active transmission.

What is the procedure for uploading the first basic test sketch to the display?

First, install the ESP32 board support in Arduino IDE. Connect the board via USB-C, select 'ESP32S3 Dev Module' as the board, and choose the correct COM port. Use the Boot button to enter download mode if needed. Then, upload a simple graphics library example (like TFT_eSPI configured for ST7701S) to verify the display and touch functionality. The built-in USB serial provides debugging output.
