NerdMiner v2
- Prefer not to pay everything at once? A 50% deposit is enough; the price is then 2% higher: deposit 866 Kč incl. VAT, and you pay the rest once the miner is on its way.
- The date reflects the factory production date plus a few days for shipping and customs.
- We set up the miner free of charge to mine into your wallet.
How the pre-order works
- You order online and receive an invoice – for the full amount or for a 50% deposit (price +2%).
- Once we receive payment, we order from the manufacturer.
- As soon as the miner has a tracking number, we let you know. With a deposit, you pay the rest at that point.
- You collect the miner in Prague, we ship it to you, or we connect it straight away on our hosting.

Description
NerdMiner v2 is an open-source gadget for bitcoin enthusiasts: a small ESP32 board with a colour display running the NerdMiner firmware and trying its luck at solo Bitcoin mining. It is not an ASIC – its hashrate is only tens to hundreds of kH/s, roughly a billion times less than a standard ASIC miner.
The chance of finding a block is therefore practically zero; it is a “lottery” with a tiny probability, not a source of income. Its main purpose is educational: you will see how pool connection and hashing work, and you get a desk display showing the BTC price and network status.
Specifications
- Algorithm: SHA-256 (solo Bitcoin mining)
- Hashrate: tens to hundreds of kH/s depending on board version and firmware
- Power consumption: approx. 1 W (device 5 V / 0.14 A / 0.71 W as measured, fan if included approx. 0.6 W)
- Power supply: USB 5 V
- Connectivity: Wi-Fi 2.4 GHz
