Compatibility
Drop-in physical replacement for every Bitcoin home miner that uses the LilyGo T-Display S3 H577 as its front-panel display, including:
- NerdQaxe+
- NerdQaxe++ Rev 6 / Rev 6.1
- NerdQaxe+ Hydro
- NerdQaxe++ Hydro
- NerdAxe Gamma
- The entire Hammer miner lineup (every SHA-256 and SCRYPT model in the Riversilicon Hammer family ships with the LilyGo T-Display S3 as standard)
- NerdMiner v2 builds.
- Other open-source ESP32-S3 miners that specify the H577 form factor
Two-Minute Browser Flash, No Soldering, No Driver Install
The screen ships blank from the LilyGo factory. Flashing runs entirely in your web browser:
- Connect the screen to your computer with a USB-C data cable. Charge-only cables 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: hold the BOOT button, briefly press and release the RESET button, then release BOOT. The board re-enumerates on USB as a serial device, ready for the flasher.
- Visit the official web flasher for your firmware:
shufps.github.io/nerdqaxe-web-flasherfor Nerd*axe,nerdminer.io/flashorbitmaker-hub.github.io/diyflasherfor NerdMiner v2. - Click “Connect,” select the LilyGo board, choose your firmware version, and click “Install.”
- Unplug the screen, plug it into the USB-C cable on your miner, and the dashboard takes over.
Future firmware updates can be performed over the air through the miner’s web dashboard. The browser flasher is only needed for the initial flash, recovery from a brick, or a switch between firmware projects.
What’s in the Box
- 1 × OEM LilyGo T-Display S3 (H577 soldered-pin), blank from the factory
- 1 X JST 1.25mm 2P
- Anti-static packaging
USB-C cable not included. The cable already on your miner is reused for installation, and any USB-C data cable works for the initial browser flash. Replacement cables are stocked in accessories.
Buy This Replacement Screen If You Need To:
- Repair a failed display on a NerdQaxe, NerdAxe, Hammer, or NerdMiner v2 (cracked LCD, dead USB-C port).
- Stock a spare for a multi-miner fleet so a downed display does not cost you uptime.
- Build a NerdMiner v2 from scratch.
- Convert between firmwares using a single physical board and the official browser flashers.
- Develop your own ESP32-S3 project: the H577 is a full development board supporting Arduino IDE, MicroPython, ESP-IDF, and PlatformIO.
