S21 Hashboard hashboard

The Bitmain Antminer S21 hash board is used to repair and replace the failed hash board of the S21 miner. When the S21 hash board fails, the miner’s hash rate will be very low or even 0, which will affect the miner’s normal operation. Therefore, quickly replacing failed hash boards can help miners resume operations quickly. In addition, the hash boards we sell can guarantee their good performance and normal hash rate.
