6 Channels IIC I2C Logic Level Converter Bi-Directional Module 5V to 3.3V For Arduino

Logic Level Shifter Bidirectional IIC 4 Way Level Translation Module description: If youve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it may be. The SparkFun bidirectional logic level shifter is a small device that safely steps a 5V signal down to 3.3V while boosting 3.3V to 5V. This level shifter can also be used for 2.8V and 1.8V devices. The real difference between this logic level shifter and our previous version is that you can successfully set the high and low voltages and safely raise and lower the same channel. Each level shifter can convert 4 high-side pins to 4 low-side pins, each with two inputs and two outputs. The level shifter is very easy to use. The board needs to be powered by two voltage sources (high voltage and low voltage) used by the system. The high voltage (eg 5V) is connected to the "HV" pin, the low voltage (eg 3.3V) is connected to "LV" and is grounded from the system to the "GND" pin. feature: Power: 5V-3V AVCC is connected to the 5V system power supply ASCL is connected to the 5V system SCL ASDA is connected to the 5V system SDA AGND connected to 5V system GND BVCC is connected to the 3V system power supply The BSCL is connected to the 3V system SCL The BSDA is connected to the 3V system SDA BGND is connected to the 3V system GND
