Tutorial: How to Use the I2C Level Converter 8 Channels

This module allows converting I2C level signals between different standards, ideal for connecting devices with different voltage levels on the same I2C network.

What you need

• Arduino or compatible I2C microcontroller
• 0.1″ cable
• Pull-up resistor (10kΩ)
• I2C devices with different voltage levels

Steps

1. 1. Installation: Assemble the module on your circuit, make sure the pins match.
2. 2. Connection: Connect the VCC and GND pins to your microcontroller.
3. 3. Data Connection: Connect the SDA and SCL pins to your microcontroller.
4. 4. Pull-up Resistance: Connect a pull-up resistor (10kΩ) between SDA and VCC, between SCL and VCC.
5. 5. Configuration: Use the SDA and SCL pins to connect I2C devices.
6. 6. Verification: Check the voltage levels of the SDA and SCL pins with a multimeter.
7. 7. Test: Connect an I2C device and verify communication.
8. 8. Debug: If it doesn’t work, check the datasheet for pin specifications.

Example code

```cpp
#include <Wire.h>

void setup() {
  Wire.begin();
  Serial.begin(9600);
}

void loop() {
  Wire.requestFrom(0x3C, 1);
  if (Wire.available()) {
    int value = Wire.receive();
    Serial.println(value);
  }
}
```

Mini project
