How it works

This microMiner implements Stratum protocol to mine on solo pool. The miner has 2 cores and implements multiple threads. One thread is used to mine Bitcoin and other is implementing stratum work and wifi stuff. Every time a new stratum job notification is received miner update its current work to not create stale shares

All configuration can be changed over a generated WifiPortal where you can modify miner settings and save them to SPIFF. The microMiner comes with several screens to monitor it’s working procedure and also to show you network mining stats.
