Specially optimized algorithm firmware enhances the hashrate to 377KH/s, improving performance compared to previous models. The display turns off after 1 minute without operation and can be reactivated by pressing any key to reduce light disturbance. Double-clicking the USER key allows switching to a desktop clock mode while the BTC lottery runs in the background. ESP32-WROOM-32 Module supports Wi-Fi and Bluetooth Low Energy. Optimized software achieves a hashrate of 377KH/s. Standalone operation: functions as a BTC lottery miner directly over Wi-Fi without requiring an external computer. Embedded design: low maintenance, high availability, high reliability, and low power consumption. Supports versatile mining options including solo and pool mining. Features an ESP32-S3R8 MCU Wi-Fi microcontroller on board.
