У меня прибор производства декабрь 2022, покупал у официалов. Из замеченных изменений: ревизия платы v8, прошивка 2.04, микроконтроллер от компании Geehy Semiconductor APM32F103ZET6, АЦП и контроллер дисплея не изменились, оперативная память переместилась под дисплей, туда же и флеш память кстати последнюю тоже заменили на MX25L12835FMI-10G. Дисплей от TIANMA TM035KDGP01.
