When your Ebit E11 miner has been running for a long time, it suddenly breaks down and cannot usually work; what is happening? Preliminary speculation may be that the control board is faulty. The control board is mainly used to receive and send the data returned by the hash board during the miner's operation. If the control board fails, it will affect the normal income of the miner. Therefore, it is recommended that you use a new control board to replace it immediately to keep the miner back up and running quickly. We sell brand new E11 control boards, and the product quality is guaranteed; welcome to contact us for purchase.
