NerdMiner V2: setup and realistic expectations
A practical introduction to ESP32 hobby mining without earnings promises.
A learning device
NerdMiner V2 is an ESP32 hobby mining device with a 2.8-inch display. Finding a Bitcoin block with this class of device is extraordinarily unlikely. A running display or increasing work counter does not mean you have earned Bitcoin. Buy it for experimentation and learning, with no promised income or payback period.
First setup
Connect the included USB-C cable for power and follow the installed firmware prompts to configure Wi-Fi and the mining service settings. Keep the device on a stable, ventilated surface. If it disconnects, check USB power and Wi-Fi before changing mining settings. Firmware screens can vary by version; contact support with a photo and version if a step differs.
Protect your wallet information
A public receiving address is different from a private key or seed phrase. Never enter a seed phrase or private key into a support message, unfamiliar website or device setup prompt. Check the instructions of the mining service you choose before using it; the store does not guarantee that service or any mining result.
Orders and help
The store listing includes the device, USB-C cable and stylus at $34.99. Allow 2 days for preparation before shipping transit. For support, include the order number, firmware version and the symptom. Avoid resetting working settings until you have recorded them.
