Understand the project

Practical overview

When it fits

Use it for a small educational Bitcoin mining project when you have a supported ESP32 board and want to explore solo-pool mining and display its activity.

Who it is for

  • People learning how Bitcoin mining and solo pools work.
  • Makers building a small ESP32 mining display.
  • Developers adapting the firmware or changing its solo-pool configuration.

Documented uses

  • Flash mining firmware to a supported ESP32 board.
  • Configure Wi-Fi and a Bitcoin wallet address.
  • Connect the device to a solo pool and view mining or network statistics on its screens.
  • Inspect activity through compatible pool pages or UART logs.
Before you choose

Requirements & limits

The project describes itself as free and open source. Its flashing instructions use an online firmware tool or downloadable repository binaries.

  • Hardware support is board-specific; choose from the repository's supported-board list and use the matching firmware binary.
  • A Bitcoin address is required before mining starts.
  • Low share difficulty means standard pools may not recognize the miner; the README recommends low-difficulty-share pools.
  • The device's screens include NerdMiner mining data, clock-style display and global mining statistics.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Configure Wi-Fi and a Bitcoin address through the miner access point

Provide the network and wallet details required for mining to start.

Before you start

  • A board already programmed with Nerdminer V2 firmware.
  • A Wi-Fi network and a Bitcoin address from the selected wallet.

Steps

  1. Connect to the NerdMinerAP access point using the password shown in the README.

  2. Set up the Wi-Fi network.

  3. Enter the Bitcoin address.

  4. Change the access-point password if needed.

Expected outcome

The miner has Wi-Fi and a Bitcoin address configured; the README says mining will not start without the address.

Guide limitations

  • The README gives a separate SD-card configuration route for boards with an SD card.
  • A custom worker name is described for public-pool.io only.
