How do I know which control board my miner has?
Open the miner and check the controller module label, or follow the identification steps in our installation guide — Amlogic, BeagleBone, CVitek and Xilinx boards each have a matching package.
Can I go back to stock firmware?
Yes. Installation is staged with power-limit protection and every model keeps a documented rollback path — you can return to a previous build at any time.
