What's New

Basic Performance Presets

Choose Stock High, Daily Boost, or Performance Test from a clean starting view. Advanced frequency, voltage, power, and per-chip controls stay separate until an experienced operator opens them.

Public Factory Recovery

Anyone can restore a supported Nano 3S to the verified factory image. Entering the same device-bound key is optional and returns an eligible used flash credit after the hardware identity is verified.

Lifetime Device Credit

The $20 firmware flash is a one-time fee per Nano. Restore that same Nano to stock to get the usable flash credit back, still locked to that device.

Persistent On-Miner Profiles

Save clocks, work mode, cooling, pool weights, voltage, and power targets directly on the Nano so the selected performance profile returns after reboot.

At-A-Glance Configuration

Every HashPower OS tab keeps the active tune, live clock range, cooling mode, pool strategy, and power target visible while you make adjustments.

On-Miner LED And Discord Alerts

Configure accepted-share, rejected-share, and block LED patterns, scheduled day/night brightness, protected Discord delivery, event categories, and hashrate summaries directly from the Nano.

Product-Scoped 24-Hour Trials

Support can issue a one-device Controller, HashPower OS, or combined trial. The server fixes the duration at 24 hours and does not expose paid-license or account administration to staff.

Support Snapshot

Copy or download a credential-free operating snapshot from the Performance page so support can review the active tune, thermal state, power, pools, and chip data without collecting passwords.

Runs directly on the miner

HashPower OS Web UI

Open the Nano from a phone or desktop and move between live status, performance controls, the eight-pool V1/V2 scheduler, and on-miner LED and Discord alerts. Pool changes are connection-tested and applied without restarting the miner process. The active-configuration strip keeps the applied tune, cooling target, pool strategy, clock range, and power target visible.

Mining Command Center Live and average hashrate, power, temperature, pools, shares, trends, and all 12 ASICs in one responsive view.
The complete on-miner performance system

Everything HashPower OS Adds

HashPower OS combines performance tuning, power visibility, adaptive cooling, live V1/V2 pool mining, board-level telemetry, persistent profiles, LED and Discord alerts, and guided recovery in one purpose-built Avalon Nano 3S interface.

Performance

Turn the Nano 3S into a configurable performance platform.

Hashrate-First Profiles Build operating profiles around stable mining performance, live work, temperature, and error quality.
Global Overclocking Apply expanded clock profiles across the complete miner from the on-device Performance page.
Basic And Advanced Views Start with clear Stock High, Daily Boost, and Performance Test presets, then reveal manual frequency, voltage, power, and per-chip controls only when you need them.
Per-Chip Frequency Control Tune each of the 12 ASIC chips individually and keep stronger chips working at their best proven frequency.
Persistent Reboot Profiles Restore clocks, chip overrides, cooling, power, and pool strategy automatically after every reboot.
Power And Cooling

See the complete operating envelope and control how the miner uses it.

Live Power Telemetry Track input voltage, current, wattage, configured power target, and available board-rail measurements in real time.
Power Target Control Set supported performance targets and keep requested power beside live measured draw on the dashboard.
Guarded Rail Tuning Use direct shared-rail adjustment with applied-state confirmation, temperature protection, and stability monitoring.
Adaptive Target Cooling Choose a chip-temperature target and let the on-miner governor make smooth fan corrections with configurable limits and emergency response.
Pool Mining

Run a flexible pool strategy directly from the miner.

Up To Eight Pools Mix as many as eight Stratum V1, V1-over-TLS, and Stratum V2 connections with individual workers, credentials, and quotas.
Quota-Weighted Mining Distribute real mining work across connected pools using the percentages you choose.
Live Pool Changes Apply validated pool changes without restarting the miner process. Unreachable replacements are rejected while the working set stays active.
Automatic Redistribution Reassign a pool's quota across healthy connections so available hashpower keeps working.
Per-Pool Performance Review connection state, accepted, rejected, stale, difficulty, best share, and effective allocation for every configured pool.
Alerts And Miner Personality

Turn mining events into clear on-device signals and useful notifications.

Share And Block LED Events Use fast blue accepted-share flashes, fast red rejected-share flashes, and a green celebration pattern when the miner reports a block.
Color And Effect Control Choose the base RGB color, brightness, and supported solid, flash, breathe, or color-cycle effects directly from the miner.
Automatic Day And Night Brightness Set daytime and nighttime brightness plus the hours when each schedule takes effect.
Protected Discord Webhook Save the webhook through a write-only field, enable or disable delivery, and send a test notification without exposing the stored URL again.
Notification Categories Select status, fan, safety, share, block, and scheduled hashrate summary messages independently.
Live Event State Review the latest LED action, delivery state, queue depth, shares, best share, temperatures, fan speed, and hashrate from the Alerts page.
Visibility And Control

Understand the miner from board level down to each ASIC.

Live And Average Hashrate Compare fast miner-side performance with a steadier average alongside shares, best difficulty, power, fan, and temperature.
12-Chip Telemetry Inspect chip temperature, requested and measured clock, voltage, PLL, matching-work counters, and available error data.
Modern Dark WebUI Move between Dashboard, Performance, Pools, Alerts, and System from a responsive interface built for desktop, tablet, and phone.
Five-Stage Mining Flow Follow the live path from the local network through pool transport, miner control, ASIC processing, and accepted or rejected share results.
Bounded Live Miner Log Filter, pause, clear, and download real miner logs without allowing the browser history to grow without limit.
Custom LCD Experience Give the Nano a distinct HashPower OS startup and live display experience that matches the on-device WebUI.
Active Configuration Strip See the live tune, clock range, cooling target, pool mode, power target, and firmware state at the top of every tab.
One-Click Support Snapshot Copy or download a credential-free diagnostic snapshot with the active profile, cooling, pool, power, and chip state for faster support.

Common questions

Avalon Nano 3S Custom Firmware FAQ

What is HashPower OS?

HashPower OS is independent custom firmware for the Avalon Nano 3S. It adds persistent on-miner performance profiles, adaptive cooling, per-chip controls, weighted pool tools, and a modern web interface.

Which ASIC miner is supported?

The current custom firmware release supports the Canaan Avalon Nano 3S. Additional models are added only after testing on real hardware.

Does HashPower OS need the Windows controller to stay open?

HashPower OS stores and applies its selected clock, cooling, power, and pool profile directly on the miner after reboot. The Windows controller adds deeper automation, benchmarking, alerts, and fleet workflows.

How does crypto checkout verify payment?

Checkout locks an exact quote, checks that the transaction paid the configured address and amount, and waits for at least two Bitcoin confirmations or the stronger finality policy configured for the selected network.

Can the Avalon Nano 3S be restored to official firmware?

Yes. The recovery page provides browser restore and the official native-tool fallback. Restoring the same registered device returns its reusable firmware flash credit while keeping that credit tied to the original device.
