2 Channel IIC I2C Level Converter Module Key Features:

  • Versatile Conversion: Two-channel bidirectional conversion between high-voltage (5V) and low-voltage (3.3V) logic.
  • One-Way Conversion Support: Facilitates 2 channels of high-voltage logic to low-voltage logic conversion.
  • Breadboard Compatibility: Can be directly plugged into a breadboard for easy use.
  • Serial Port Communication: Enables direct communication between 5V and 3.3V levels on the serial port.
  • High Baud Rate: Supports stable communication at up to 28800bps.
  • Broad Compatibility: Suitable for bidirectional conversion of UART, IIC, 1-wire, SPI, and other bus signals between 3V and 5V levels.

Compatibility Connections of 2 Channel IIC I2C:

  • AVCC: Connects to 5V system power.
  • ASCL/ASDA: Connects to 5V system SCL/SDA.
  • AGND: Connects to 5V system GND.
  • BVCC: Connects to 3V system power.
  • BSCL/BSDA: Connects to 3V system SCL/SDA.
  • BGND: Connects to 3V system GND.

Application Range:

  • Ideal for serial communication between 5V and 3.3V microcontrollers.
  • Useful for 3.3V serial downloaders communicating with 5V MCU serial ports.
  • Facilitates communication between 5V MCUs and 3.3V application modules.

Common applications for I2C include:

  • Reading Hardware Monitors: Ideal for interfacing with system hardware to monitor various parameters like temperature, voltage, and fan speeds.
  • Sensor Communication: Facilitates data transfer between microcontrollers and a wide range of sensors, ensuring compatibility between different voltage levels.
  • Real-Time Clock Interfaces: Essential for interfacing with real-time clock modules that require level shifting for accurate timekeeping and data logging.
  • Actuator Control: Useful in robotic applications or systems where actuators need to be controlled by a microcontroller operating at a different voltage.
  • DACs and ADCs Interaction: Enables communication with digital-to-analog converters (DACs) and analog-to-digital converters (ADCs) in audio applications, signal processing, and more.
  • Serial Data Transfer to/from Sensors: Streamlines data transfer processes in complex systems involving multiple sensors, ensuring data integrity and system reliability.
  • EEPROM Programming: Supports programming of EEPROMs in various electronics, allowing for efficient data storage and retrieval.
  • Polling/Receiving Sensor Data: Enhances capabilities in systems that require regular polling of sensors or need to receive data from multiple sensors, maintaining stable operation across different voltage levels.

Wiring Instructions:

  • HV: Connect to 5V power supply.
  • LV: Connect to 3.3V power supply.
  • GND: Common ground for both power supplies.
  • RXI/RXO: Input 5V TTL, output 3.3V TTL.
  • TXI/TXO: Two-way conversion between 3.3V TTL input/output and 5V TTL input/output.
