FRESH INSTALLATION
Connect. Install. Configure.
- Use desktop Chrome or Edge with a USB data cable. Close Arduino Serial Monitor and other software using the board.
- Confirm you have a Guition JC4827W543 with ESP32-S3, the 4 MB flash layout and OPI PSRAM. The installer detects the chip family, not the exact display model.
- Choose Connect, select the board’s serial port and follow the installer prompts.
This is a fresh installation. It replaces the full flash image, including saved Wi-Fi, API credentials, preferences and touch calibration. You will need to configure the display again. To keep an existing matching installation’s settings, use the app-only download and USB update instructions below.
