4 Channel IIC I2C Logic Level

If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices.

Q & A

4 Channel IIC I2C Logic Level is a part of the MCU development board, and equipment is 3.3V work, but also a microcontroller development board and equipment, sensors, etc. are the 5.0V power supply, so when the two need to communicate, there are 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.

  • To achieve direct serial 5V and 3.3V level communication.
  • The maximum stable communication baud rate is 28800bps.
  • Can achieve UART, IIC, 1-wire, SPI and other bus signals 3V-5V level of the two-way conversion.
  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
  • If the high-pressure and low-voltage areas of the power have been a total, this module G only needs to take aground.
  • The conversion module is equivalent to a straight line, each port is a one-to-one correspondence, but the voltage side 2 is not the same,
  • Thus realizing the communication between the different levels.
  • the module can not be used as a regulator or transformer function and can only be used for the IO port
  • A level between the small current communication.
  • This module pin-pin has no welding, but there are matches.

Package included: 1 x 4 Channel IIC I2C Logic Level 2 x 6 Pin Male Header Strip
