Optimized Software that achieves a higher Harshrate of 950KH/s (the hashrate firmware is being continuously upgraded). Hashrate increases by 1600% more than other boards from , which means 1600% more chances of winning.(the hashrate firmware is being continuously upgraded) Standalone: can work as a BTC lottery miner directly over WiFi. No External computer is needed. Embedded: low cost, low maintenance, high availability, high reliability, low power. Specially optimized algorithm firmware enhances the hashrate to 950KH/s (Floating up and down) (the hashrate firmware is being continuously upgraded), increasing the probability of winning the lottery by 1600% ( V2 only 55KH/s). Versatile: Solo/pool mining. Due to different batches, there may be differences in product appearance, color, and printed text, which not affect the use.
