# nano3-os: reconstructing the Avalon Nano 3 mining protocol

> nano3-os reconstructs the Canaan Avalon Nano 3's K230-to-K210 mining protocol from analysis of btcminer and UART captures. Its notes cover CN frames, CRC-16/XMODEM, job bursts and nonce reports; a Go daemon uses that protocol to run the miner with a Stratum V1 pool, board controls and a web dashboard.
