Crypto Mining with Arduino, and is it Worth it?

What is Crypto Mining?

Crypto mining or cryptocurrency mining is the process of validating and verifying transactions on a blockchain network and adding them to the blockchain’s public ledger. Miners, individuals or entities, use specialized computer hardware and software to solve complex mathematical puzzles, known as cryptographic algorithms. Successful miners are rewarded with cryptocurrency tokens for their efforts.

Can you Mine with Arduino?

Short answer, yes! Long answer, why would you want to?

If you are just wanting to try it and learn something new and have no real intentions of earning any real profit, then give it a try.

Here are some reasons why you just shouldn’t bother:

  • Limited Processing Power: Arduino boards have very limited processing power compared to dedicated mining hardware. They are not capable of performing the complex mathematical calculations (hashing) required for cryptocurrency mining efficiently.

  • Insufficient Memory: Arduino boards also have limited memory, which is necessary for storing transaction data and blockchain information. Cryptocurrency mining requires access to a significant amount of memory to manage the blockchain and process transactions.

  • Energy Efficiency: Cryptocurrency mining is highly energy-intensive, and Arduino boards are not optimized for energy efficiency. Mining on an Arduino would likely consume more power than it could generate in cryptocurrency rewards.

  • Lack of Compatible Mining Software: There is no mining software available for Arduino boards, as they are not suitable for mining purposes. Cryptocurrency mining software is designed to work with specific hardware architectures, which Arduino does not possess.

  • Network Connectivity: Cryptocurrency mining requires a stable and high-speed internet connection to communicate with the blockchain network. Arduino boards lack the necessary networking capabilities for this task.


My Experience

I used 6 D1-mini boards for this project as they have the Wi-Fi chip for a direct network connection. They Worked well but as I said don’t expect to make any money this is just for fun.

As you can see from the image below, you can mine with Arduino. It is however relatively pointless if you’re looking to earn any profit from mining.

Where to Start?

If you want to learn how to mine with Arduino and earn no money whatsoever doing so, you can get started here:


While this was an interesting project to build, you won’t earn enough money to cover the cost of the components or electricity used over time. If you’re just looking for something new to make, this could be a fun project for you to build. But, if you’re looking to invest, this is not the way!

Happy Tinkering!
