8-Way Level Conversion Module for Raspberry Pi

brand: SainSmart SKU: 101-40-125

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
  • Only ship to US

(Take 3.3V, 5V conversion for example )

  • VCCA connects to Raspberry Pi 3.3V power supply
  • VCCB connects to 5V power supply(It can be external 5V power supply )
  • GND connects to negative pole, two power supplies common-grounded
  • Ax inputs Raspberry Pi 3.3V TTL level, Bx outputs 5V sensor module TTL  level
  • Bx inputs 5V electronic module TTL level, Ax outputs Raspberry Pi 3.3V TTL level

Worked great for smart lamp build

I built an Alexa controlled smart lamp based on a Raspberry Pi 3 running fauxmo and a Sainsmart 5v relay board. This board worked great converting RPI 3.3v GPIO lines to the 5v relay control. It did take up a lot more space than if the pins were at 90 degrees to the converter board.
