ESP32 Bitcoin Miner for Solo Lottery with 2.8-Inch Touch Display and WiFi
Run Bitcoin solo lottery mining without a computer. This compact ESP32-based miner ships with NMMiner firmware, requires no license, and connects directly to your WiFi to operate independently. It draws under 1W, delivering a low-power, plug-and-play experience.
The 2.8-inch full-color touch display provides real-time mining metrics at a glance, including hashrate, block status, uptime, and network connectivity. The screen auto-dims after one minute of inactivity to reduce light pollution, and you can wake it with any key. Double-click the USER key to switch to desktop clock mode while mining continues in the background.
Hashrate and firmware — Deeply optimized NMMiner firmware achieves a hashrate of 1000KH/s, significantly higher than standard NerdMiner V2 builds at 55KH/s. A higher hashrate increases the statistical probability of hitting the solo block reward in the lottery mining model. Free lifetime firmware upgrades accompany the NMTech firmware.
Standalone WiFi operation — Powered by the ESP32-D0WD-V3 MCU with integrated 802.11 b/g/n WiFi and Bluetooth 4.2, it operates completely independently over WiFi with no PC or external hardware required. Supports both solo and pool mining modes.
