KNACRO 8Channel 5V 33V IIC UART SPI TTL BiDirectional Logic Level Converter

8-channel high-voltage and low-voltage logic bidirectional logic conversion, two-way conversion between Ax and Bx. Conversion level range: 1.8V-6V. Module size: 28mm X 27.5mm. Weight:3.3g/0.12oz. Instructions: ( for example 3.3V, 5V system conversion). VCCA connect to 3.3V power supply. VCCB connected to 5V power supply. GND negative one, two power supply common ground. Ax input 3.3V TTL level,Bx will output 5V TTL level. Ax input 5V TTL level,Bx will output 3.3V TTL level. Package Included: 1 x 8-Channel 5V/3.3V IIC UART SPI TTL Bi-Directional Logic Level Converter.
