Braiins OS is the very first fully open-source, Linux based system for cryptocurrency embedded devices. Luxor's Bitcoin Mining Pool supports the operating system and ASIC Boost.
It is currently available for Bitmain Antminer S9, S9i, S9j; and the Dragon Mint T1 (with G19 or G29 control board).
The benefit of using Braiins OS is that you can run an open and auditable piece of software with AsicBoost enabled. It also has features like advanced overclocking and full fan control. Ultimately we recommend it to enjoy significant power savings and performance improvements.
