Both were purchased new from Akizuki about 10 years ago. They were used at the time and functioned without any problems. After using them for about a year, they were stored for a long period. Before listing, I confirmed that they powered on when connected to a PC via USB, but other operations have not been checked. They will be sent as shown in the photos. The legs at the four corners of the circuit board will be removed and included. Please consider this item, understanding that it is a used product. #ElectronicWork #ElectronicComponents #ElectricalCircuits
