V1.8.3-FX1 RC1
An unofficial open-source NerdMiner V2 fork. Physically tested on the ESP32_2432S028_2USB (classic ESP32, 4 MB flash). Other variants are not validated.
Up to ~446 kH/s measured on our test unit, compared with ~340 kH/s on stock firmware. Results vary by board and setup.
Update to FX1 — keep my configuration
Recommended for the supported board with a compatible existing partition layout. This writes only the application at 0x10000; it does not include NVS, SPIFFS, bootloader or partition-table files.
- Connect your NerdMiner to this computer with a data-capable USB cable.
- Click the button, choose its serial device, then choose Install.
- When asked “Erase device?”, leave the box unchecked and click Next. Erasing would delete your settings.
- Keep USB connected until flashing finishes. The miner will reboot.
Do not select “Erase device”. The recommended update preserves existing Wi-Fi, mining address and pool settings only on a compatible layout. Back up the device first if the existing layout is uncertain. This is RC/Beta firmware.
Advanced: fresh install / recovery
Settings can be lost. The factory image starts at 0x0000 and spans the NVS/configuration region. Use it only for a deliberate clean install or recovery—not to update a configured miner.
