Five boards in production, from a 200 G single-ASIC miner on USB-C to 1.5 T. Firmware, manuals and the browser flasher all live here — every release indexed with its file size and SHA256.
Five boards in production. Find the name on your device or its box, then open that model.
Compact single-ASIC miner. 200G at roughly 8.9 W, powered over USB-C — the smallest of the ASIC line.
Entry ASIC model with a full touchscreen. 200G at about 10 W — quiet enough to sit on a desk and cheap to run around the clock.
The high-hashrate model — 5–7× the output of U1 at 22–27 W. Better hashes per watt, at the cost of heat and noise.
Mid-size single-ASIC miner with a colour screen. 200G at about 8.9 W on a 12 V DC supply.
Runs on the off-the-shelf CYD board. The ESP32 hashes by itself, so it is a desk display and learning board — and the firmware is fully open source.

Which one you need depends on what state the device is in.
Download the .zip for your model, open the miner's web UI, go to Settings → Firmware and upload it. Your settings are preserved. This is the right choice 95% of the time.
For a bricked board, a device that will not boot, or a U1/U2 whose CD KEY was wiped. Needs a USB cable and Chrome/Edge — the flasher runs entirely in the browser using the local image files.
Open flash tool →Only U1 and U2 carry a CD KEY (Settings → System). An OTA keeps it, a full erase wipes it, and a lost key cannot be recovered. N8-T, D12, N5 and S1 have no key — nothing to save.

Bilingual PDF manuals for the All / N / D series, plus tutorials and PCB files.
