Can I mine Monero on an Orange Pi or other ARM single-board computer?

Yes, you can mine Monero on some Orange Pi boards and other ARM single-board computers, but not every model can run suitable mining software. A modern board with a 64-bit processor, enough memory, and good cooling is best treated as a learning project—not a dependable way to earn money.

Check your exact board, not just its name

Orange Pi is a family of small, complete computers on a single circuit board. Models differ widely, so advice for one Orange Pi may not apply to yours. The same is true for Raspberry Pi and other ARM boards.

Before you start, check these points:

• Processor: Look for a 64-bit ARM processor, often described as ARMv8 or AArch64. ARM is the processor family used by many small computers and phones.
• Operating system: Use a 64-bit Linux system supported by your board. A 64-bit processor running a 32-bit system is not enough for the usual ARM64 mining setup.
• Memory: At least 4 GB of RAM is a practical starting point for RandomX fast mode. RAM is the working memory your programs use.
• Software support: Check that your chosen miner supports your processor and operating system.

Older boards with little memory or only a 32-bit processor are generally poor candidates.

Why Monero is demanding on small boards

Monero uses RandomX, the calculation system that miners run to help secure its network. It favors CPUs—the main processors in computers—but that does not mean every CPU performs well.

RandomX fast mode needs a roughly 2,080 MB dataset, plus memory for its cache, mining software, and operating system. That makes a 2 GB board too cramped for a normal fast-mode setup.

Light mode uses a 256 MB cache instead of the large dataset, but mining is much slower. It can make experiments possible on a smaller board without making that board financially useful.

RandomX also needs about 2 MB of L3 cache per mining thread for efficient performance. L3 cache is fast memory inside the processor; a thread is one stream of work. Many ARM boards have limited shared cache, so eight CPU cores do not automatically mean eight effective mining threads.

Native software is usually better than a browser

On a compatible board, native mining software—software running directly on Linux—is generally the more practical choice. XMRig supports ARM64, although you may need to build it from source code rather than download a ready-made package for your board.

Browser mining adds another limitation. A browser can restrict access to processor features and memory settings that help RandomX run efficiently. Some websites also mine something else and pay you in XMR, which is not the same as mining Monero directly.

For any mining service, check:

• What calculation your device actually performs.
• Its fees and minimum payout.
• Whether your likely earnings can realistically reach that payout.

You should never need to give a mining website your wallet’s recovery phrase.

Plan for heat and tiny returns

Use a suitable power supply and a heatsink, usually with a fan. Sustained mining can cause thermal throttling, where your board slows down to avoid overheating.

Start with a few threads. Measure speed, temperature, and power use before adding more. More threads can increase heat without improving results.

Check a live mining calculator using your measured speed and electricity cost. Include cooling and hardware costs if you are buying specifically to mine.

The bottom line

Your ARM board can be a useful Monero experiment if it has compatible software, sufficient memory, and cooling. Use hardware you already own, measure its performance, and do not assume low power consumption means a profit.
