NOYITO 8-Channel IIC UART SPI TTL Bi-Directional Logic Level Conversion Module 3.3V-5V 5V-3.3V - Bent Pins -2Pcs

Product Features: 8-Channel high-voltage logic and low-voltage logic bidirectional conversion, Ax and Bx two-way mutual conversion. Conversion level range: 1.8V-6V Module size: 28mm X 27.5mm Special Note: This product is a level conversion module is not a power conversion module! Need to connect 5V and 3.3V two power supplies. Instructions for use: Take 3.3V and 5V mutual conversion as examples VCCA connected to 3.3V power supply. VCCB connected to 5V power supply. GND is connected to the negative pole of the power supply. The two power supplies are common ground. Ax inputs 3.3V TTL level, Bx will output 5V TTL level. Bx inputs 5V TTL level and Ax will output 3.3V TTL level. Package Included: 2pcs 8-Channel IIC UART SPI TTL Bi-directional Logic Level Conversion Module
