It is commonly used to interface \u003cstrong\u003e3.3V microcontrollers\u003c\/strong\u003e with \u003cstrong\u003e5V sensors, modules and development boards\u003c\/strong\u003e.\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe module provides \u003cstrong\u003efour independent signal channels\u003c\/strong\u003e. Each channel can translate a low-voltage digital signal to a higher logic level and also translate a higher-voltage signal back to the lower level. This bidirectional operation makes it especially useful for two-way communication interfaces.\u003c\/p\u003e\n\u003cp\u003eThe common version of this module uses \u003cstrong\u003eBSS138 N-channel MOSFETs\u003c\/strong\u003e with onboard pull-up resistors. Separate high-voltage and low-voltage reference pins allow the board to determine the required logic level on each side. \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eFor a typical 3.3V-to-5V application, connect the \u003cstrong\u003eLV pin to 3.3V\u003c\/strong\u003e, the \u003cstrong\u003eHV pin to 5V\u003c\/strong\u003e, and connect both systems to a common ground. The signal pins on the LV side are then matched with their corresponding channels on the HV side. \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe converter is suitable for digital communication signals such as \u003cstrong\u003eI²C, UART, 1-Wire and other relatively low-speed logic interfaces\u003c\/strong\u003e. Some suppliers also list it for SPI, but performance at higher signal speeds depends on the module’s pull-up resistors, wiring length and connected devices. \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThis module is widely used when connecting 5V Arduino boards to 3.3V devices such as ESP32, ESP8266, Raspberry Pi, STM32 modules, displays and sensors.
