  • 8 Channel 5V 3.3V IO Bi-directional Interchange IIC UART SPI TTL Logic Level Converter for Raspberry Pi Level Conversion Module

    The V2 upgrade version reads as follows:
    1.VCCA and VCCB add a set of power supply interface, (for example: PI connected to the 5V sensor. V1 version VCCA, VCCB connected 3.3V and 5V power supply, there is no extra power port to the 5V sensor power supply .V2 new version 2 side increase A set of power ports .5V sensor power can be inserted directly on the VCCB, users do not have their own DIY power cord.)
    2.V2 version of the power interface to increase the 4 filter capacitor, relative to V1 more stable and reliable.

    Product Features:
    As the GPIO is 3.3V, so then the conventional 5V sensor is very convenient. So this product to achieve 8-channel high-voltage logic and low-voltage logic bi-directional conversion, to achieve Ax and Bx bidirectional turn.
    Conversion level range: 1.8V-6V
    Instructions for use: (3.3V, 5V interchange for example)
    VCCA picks up raspberry 3.3V power supply
    VCCB 5V power supply (can be an external 5V power supply)
    GND connected to the power supply negative, two power supply ground
    Ax input raspberry to send 3.3V TTL level, Bx will output 5V sensor module TTL level
    Bx input 5V electronic module TTL level, Ax will output raspberry to send 3.3V TTL level
