Specifications:
1.Since the Raspberry Pi GPIO is 3.3V, it is inconvenient to connect a conventional 5V sensor. Therefore, this product realizes 8-channel high-voltage logic and low-voltage logic bidirectional conversion, realizing Ax and Bx bidirectional mutual conversion.
2.Conversion level range: 1.8V-6V
Instructions:
VCCA connects Raspberry Pi 3.3V power supply
VCCB is connected to 5V power supply (can be external 5V power supply)
GND is connected to the negative pole of the power supply.
Ax input Raspberry Pi 3.3V TTL level, Bx will output 5V sensor module TTL level
Bx input 5V electronic module TTL level, Ax will output Raspberry Pi 3.3V TTL level
