Can I run a Monero node on a Raspberry Pi 4 or 5?
Yes, you can run a Monero node on a Raspberry Pi 4 or 5, preferably with at least 4 GB of memory and an external solid-state drive (SSD). A Pi 5 is the better choice if you are buying new, but a Pi 4 you already own can work well. Running a node helps you check Monero transactions yourself; it does not earn mining rewards on its own.
What your Pi needs
A Monero node runs software that downloads and checks the blockchain—the shared record of transactions. For a practical setup, you want:
- A 64-bit operating system. Use a supported 64-bit Linux system, such as Raspberry Pi OS Lite or Ubuntu Server.
- At least 4 GB of memory. An 8 GB model gives you more breathing room, especially if you also run P2Pool.
- An external SSD. Connect it through USB 3 on either Pi, or use a suitable NVMe adapter on a Pi 5. NVMe is another way to connect fast storage.
- Reliable power and cooling. A proper power supply and a fan help prevent crashes and heat-related slowdowns.
- A steady internet connection. Ethernet is usually more dependable than Wi-Fi for an always-on node.
You can keep the operating system on a microSD card, but put the blockchain on the SSD. A card’s slow performance and limited write endurance make it a poor choice for that job.
Storage and the first sync
Before choosing your SSD, check the current Monero blockchain size. Leave substantial room for growth rather than buying a drive that barely fits today.
You can run a pruned node, which discards some older transaction data after checking it. Pruning greatly reduces storage use, and your node still verifies the blockchain. However, it cannot supply other nodes with every piece of historical data.
Enable pruning from the start if saving space matters to you. Switching an existing database to pruning does not necessarily shrink the space already allocated on disk without additional steps.
The first sync, when your Pi downloads and verifies the existing blockchain, is the demanding part. Expect days rather than hours, and potentially much longer on a slower setup. An SSD, good cooling, and a Pi 5 help. Keeping up afterward is much easier.
How this fits solo mining and P2Pool
Your Pi can be the node that a separate mining computer uses. That is often a better arrangement than asking the Pi to do everything.
- Solo mining: Your miner uses your node to work on blocks. You only receive a reward if you find a block, which can mean an extremely long wait with a small miner.
- P2Pool: This decentralized mining pool shares rewards without a central pool operator holding your earnings. You can run its software alongside your node, with a miner connecting to P2Pool.
Monero mining uses RandomX, a calculation designed to favor general-purpose processors. Pi processors can run mining software, but their limited performance makes them poor choices for meaningful earnings. Running a node does not improve your miner’s calculation speed.
The bottom line
A Pi 4 or 5 with enough memory, an SSD, and reliable cooling makes a useful low-power Monero node. Keep its software updated, and do not expose its wallet-facing control interface to the public internet. Treat the Pi as your transaction-checking and mining-support machine—not as a source of easy mining income.
