with NerdMiner
The cheapest entry point into Bitcoin mining. Not to earn rewards, but to truly understand what mining means and experience it for yourself.
Learn by doing
Its goal isn't to mine a block. It's to teach you what mining actually means: SHA-256 proofs-of-work, difficulty targets, solo vs pool, all running live on your desk.
Any ESP32 board
Works out of the box on 23+ ESP32-compatible boards. From a spare dev kit to a dedicated display, if it runs ESP32, it can run NerdMiner.
Near-zero cost & power
Under 5W consumption. A ~$10 dev board is all you need to start. No risk, no noise, no large upfront investment. Just a miner you can hold in your hand.
Fully open source
Firmware, schematics, and PCB layouts, all public. Build it, fork it, learn from it, or use it in the classroom.

What builders and educators say about NerdMiner
"We taught kids how Bitcoin mining works using NerdMiners in class. Watching their faces when the display showed their first valid share was priceless. This is what Bitcoin education looks like."
"I started with a cheap ESP32 board and NerdMiner. Within an hour I understood difficulty adjustments, nonces, and why mining is hard — better than any article I had read before."
"If you want to understand Bitcoin mining from the ground up, NerdMiner is the most approachable tool out there. A working miner in your hands for under $15 — no excuses not to try."
