Specially optimized algorithm firmware enhances the hashrate to 377KH/s. 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. Equipped with an ESP32-WROOM-32 module supporting Wi-Fi and Bluetooth Low Energy. Optimized software achieves a hashrate of 377KH/s. Standalone design allows direct operation as a BTC lottery miner over Wi-Fi without requiring an external computer. Embedded system offers low cost, low maintenance, high availability, high reliability, and low power consumption. Supports both solo and pool mining.
