Now you can connect your 3.3V logic level devices to your 5V MCU and vice versa using 8 Channel Logic Level Converter.
Features & Specifications:
Logic Level converter makes it possible to connect 3.3V (or even lower voltage sensors) to 5V micro controllers like the Raspberry Pi. With this module you can easily connect different logic voltage levels together for bi-directional communication on up to 8 channels, allowing you to use low-voltage sensors with a 5V micro-controller.
8 bidirectional channels
Easily connect 3.3V sensors and devices to 5V microcontrollers
Pass-through GND connection
Conversion electrical level range: 1.8V-6V
(Take 3.3V, 5V conversion for example )
VCC A connects to Raspberry Pi 3.3V power supply
VCC B connects to 5V power supply(It can be external 5V power supply )
GND connects to negative pole, two power supplies common-grounded
A x inputs Raspberry Pi 3.3V TTL level, Bx outputs 5V sensor module TTL level
B x inputs 5V electronic module TTL level, Ax outputs Raspberry Pi 3.3V TTL level
