Конвертер логики — высокоскоростной, двунаправленный 3.3V-5V, 4-x канальный
Модуль представляет собой конвертер сигналов с 5в логики на 3.3в логику и обратно. На плате имеетсяя 4 независимых канала связи и 2 шины питания на 5в и 3.3в.
This logic level converter features four high speed bi-directional 4 channels, allowing for safe and easy communication between devices operating at different logic levels. It can convert signals as low as 1.8 V to as high as 5 V and vice versa, and its four channels are enough to support most common bidirectional and unidirectional digital interfaces, including I²C, SPI, and asynchronous TTL serial.
