    4-way 3.3V / 5V bi-directional level conversion module

    As part of the MCU development board and equipment is 3.3V work, but also a microcontroller development board and equipment, sensors, etc. is the 5.0V power supply, so when the two need to communicate, there is a work voltage inconsistencies, so that users Up inconvenient. This product is designed to solve this problem and solve this problem. This module provides the possibility of bridging in 3.3V and 5.0V different devices.


    Product Application:

    The Communication of 1,5V Single - chip Microcomputer and Serial Port of.

    2,3.3 V serial port to download and 5V microcontroller serial communication.

    3,5V MCU and 3.3V application module serial communication.


    Product Features:

    1, comes with 3.3V voltage, with power indicator Power input with anti-reverse protection, and can not provide more than 150mA of current.

    2, to achieve direct serial 5V and 3.3V level communication.

    3, the maximum stable communication baud rate 28800bps.

    4, can achieve UART, IIC, 1-wire, SPI and other bus signals 3V-5V level of the two-way conversion.

    5, Compatibility:

    (1) AVCC 5V system power supply (2) ASCL 5V system SCL

    (3) ASDA connected 5V system SDA (4) AGND then 5V system GND

    (5) BVCC then 3V system power supply (6) BSCL then 3V system SCL

    (7) BSDA connected 3V system SDA (8) BGND then 3V system GND

    note:

    1, if the high-pressure area and the low-voltage area of the power has been a total of this module G only need to take a ground.

    2, the conversion module is equivalent to a straight line, each port are one-to-one correspondence, but the voltage is not the same as the two sides,

    Thus realizing the communication between the different levels.

    3, the module can not be used as a regulator or transformer function can only be used for IO port

    Level between the small current communication.

    4, the module pin-pin no welding, but there are matching.
