8 Channels IIC I2C level converter module

8 level conversion module two-way conversion between 3.3V and 5V IO access 5V sensor for Pi
Product Features:
? Since the Raspberry Pi GPIO is 3.3V, so then the conventional 5V sensor inconvenient. Therefore, this product to achieve 8-channel high-voltage and low-voltage logic bidirectional logic conversion, two-way conversion between Ax and Bx.
? Conversion level range: 1.8V-6V
Description :( with 3.3V, 5V system conversion as an example)
? VCCA pick raspberry pie 3.3V power supply
? VCCB connected to 5V power supply (may be an external 5V power supply)
? GND negative one, two power supply of land
? Ax input Raspberry Pi 3.3V TTL level, Bx output 5V TTL level sensor module
? Bx input 5V TTL level electronic modules, Ax Raspberry Pi 3.3V TTL output level.
