ESP32 Bitcoin Solo Lottery Miner with 2.8-Inch Touch Display, 1000KH/s Optimized Hashrate and Standalone WiFi Operation

Compact ESP32-based Bitcoin solo lottery miner running NMMiner firmware — no license required, no external computer needed. Connects directly to your WiFi network and runs independently with under 1W power consumption. The 2.8-inch touch display shows real-time mining metrics including hashrate, block status, and network connectivity at a glance.

1000KH/s Optimized Hashrate Deeply optimized NMMiner firmware achieves a hashrate of 1000KH/s — significantly higher than standard NerdMiner V2 builds at 55KH/s. Higher hashrate increases the statistical probability of hitting the Bitcoin solo block reward in the lottery mining model.

No License Required — Free Lifetime Upgrades NMMiner firmware requires no license. The NMTech team provides free firmware upgrades to every new version — no additional costs after purchase.

Standalone WiFi Operation Powered by the ESP32-D0WD-V3 MCU with built-in 802.11 b/g/n WiFi and Bluetooth 4.2. Operates completely independently over WiFi — no PC, no external hardware required. Supports both solo and pool mining modes.

2.8-Inch Touch Display Full-color touchscreen displays real-time mining data including hashrate, block status, uptime, and connection status. Screen auto-dims after 1 minute of inactivity — press any key to wake. Double-click the USER key to switch to desktop clock mode while mining continues in the background.
