Canaan Avalon A15 Series
The Avalon A15 series, led by the A1566 model, was Canaan's flagship SHA-256 ASIC lineup through 2024, later extended with the more efficient A15 Pro variant. While since succeeded by the A16 series, A15-generation machines remain widely deployed across mining farms due to their competitive price-to-performance ratio on the secondary market.
SHA-256 Algorithm on the A15 Platform
Like all current Avalon machines, the A15 series mines using the SHA-256 algorithm. The A15 Pro variant improved on the base A1566's efficiency, bringing it down to roughly 16.8 J/TH — a meaningful step toward the efficiency levels later achieved by the A16 series.
The Avalon A15 series operates within the following approximate technical parameters:
Algorithm: SHA-256
Supported Coins: Bitcoin (BTC), Bitcoin Cash (BCH), and other SHA-256 coins
Hashrate Range: approximately 185 TH/s to 215 TH/s
Power Consumption Range: approximately 3600 W to 4255 W
Energy Efficiency: roughly 16.8-23 J/TH depending on variant
Release Period: 2024-2025
Cooling System: air-cooled
Network Connection: Ethernet
Power Density of the Avalon A15 Series
At over 3.6-4.2 kW per unit, A15-series machines run hot and loud compared to newer, more efficient flagships, and benefit significantly from proper airflow or dedicated hosting rather than casual home deployment.
What Users Say About the Avalon A15 Series
The A1566 and A15 Pro are generally described by miners as solid, if unremarkable, workhorses — not best-in-class efficiency, but dependable and increasingly affordable on the used market as newer generations arrive.
Custom Firmware for Canaan Avalon A15 Series
As an established generation that has been on the market for a while, the A15 series has reasonable third-party firmware support, with tuning profiles available to improve on stock efficiency and fan behavior.
Overclocking and Undervolting the Avalon A15 Series
Undervolting is particularly relevant for the base A1566 model, given its higher stock J/TH figure compared to the A15 Pro — many operators report meaningfully better economics after trimming voltage and frequency to bring efficiency closer to Pro-tier levels.
Longevity and Resale Value
As a previous-generation flagship, A15-series units are now available at a discount on the secondary market, making them an attractive entry point for budget-conscious miners willing to trade some efficiency for a lower upfront cost.
For miners prioritizing lower acquisition cost over maximum efficiency, the Canaan Avalon A15 series remains a viable SHA-256 ASIC option, especially on the used hardware market.
