H6OS control board and P221C power supply manifest

To celebrate the Chinese National Day, starting today, all HiYomei staff will have a 7-day holiday, and the editor will also have a holiday together to update customer orders for goods in September before the holiday.   
There are H6OS and P221C power supply, which are the official authentic source of Whatsminer.   
Before the shipment and the preparation of the cooperation contract, from the beginning of the month to the agreement for delivery at the end of the month, we have been negotiating for nearly a month, from the preparation of the contract to the determination of the customer, and then negotiate the delivery time, which is determined by the customer.   
At the same time, we also thank customers for their trust in HiYomei and welcome potential customers for cooperation. You can check our background before placing an order to avoid being cheated. You can ask us directly through Whatsminer after-sales whether we are partners of accessories manufacturers.
