Specially optimized algorithm firmware enhances the hashrate to 411KH/s, improving performance compared to similar devices. The display turns off after 1 minute without operation and can be reactivated by pressing any key to reduce light pollution. By double-clicking the USER key, users can switch to a desktop clock mode while BTC mining continues in the background. Features an ESP32-WROOM-32 module with Wi-Fi and Bluetooth LE connectivity. Optimized software delivers a hashrate of 411KH/s. Standalone design allows direct operation as a BTC miner over Wi-Fi without requiring an external computer.
