"Genuine Screen, Bitcoin Mining Vision!"
The LilyGo T-Display S3 (H577) is a 1.9" ESP32-S3 full-color LCD display module with pre-soldered header pins, serving as the OEM original screen for series such as the NerdQaxe++ Remastered Edition. It features a Sitronix ST7789V driver chip, 16MB Flash, and 8MB PSRAM, simply flash the firmware and it's ready to go.
Key Features
- Plug & Play: Pre-soldered 2.54mm pin header, mount it and use it immediately. Highly recommended to keep one as a hot spare if you run multiple miners.
- Premium Display Specs: 1.9" full-color IPS LCD, 170×320 pixels, ST7789V driver, with backlight control — decent and stable visual output.
- ESP32‑S3 Development Board: ESP32‑S3R8 (up to 240MHz) + 16MB Flash + 8MB PSRAM, compatible with Arduino / MicroPython / ESP‑IDF / PlatformIO projects.
- Hassle-Free Flashing: Supports the official web-based flashing tool (Chrome / Edge / Opera) — firmware swapped in minutes.
- Expansion-Friendly: Reserved I²C-type interface (STEMMA QT / Qwiic compatible), plus onboard charging management for a 3.7V LiPo battery — convenient for future mods and hardware expansions.
- Authenticity Guaranteed: Factory-direct from LilyGo — genuine OEM replacement for the stock OLED screen.
2-Minute Quick Flash / Upgrade Guide
The screen leaves the LilyGo factory blank. The entire flashing process runs right inside your web browser:
- Connect the screen to your PC using a USB-C data cable. A charge-only cable will not work.
- Open Chrome, Edge, or Opera. Firefox and Safari do not support the Web Serial API and cannot flash ESP32-S3 boards.
- Put the board into Download Mode: press and hold the BOOT button, briefly press and release the RESET button, then release the BOOT button. The board will re-enumerate over USB as a serial device and become flashable.
- Launch the official web flasher to get your firmware:
shufps.github.io/nerdqaxe-web-flasher — this one is for NerdQaxe.
- Click "Connect", select the LilyGo board, pick your firmware version, then click "Install".
- Unplug the screen, plug it into the miner's USB-C cable, and the dashboard will take over automatically.
The browser-based flasher is intended for first-time flashing, recovery from a bricked state, or switching firmware versions only.
Compatible Use Cases
