：内置了3.3V电压转换电路，逻辑电平稳定在3.3V。这是比较适合新手入门的“安全版”。因为绝大多数25系列SPI Flash芯片（如常见的Winbond W25Q系列，系统固件的存储介质）以及24/25系列EPROM/Flash的基准电压均为3.3V。
While newer iterative versions exist, version 2.1.0.19 remains highly sought after because of its rock-solid stability, massive built-in chip database, and clean interface. It fixes many verification errors that plagued earlier editions and optimizes the writing speeds for 25-series SPI flash chips commonly found in modern computer BIOS chips.
