Logic Level Converter

8 channel Level Switching (3.5V to 5V) IO Module Logic Level Converter is able to convert signals from 5V down to 3.3V (and vice versa) meaning you can safely use 5V or 3.3V devices with the Raspberry Pi (compatible). CityTech BD 

Because raspberries GPIO is 3.3 V, so regular 5 V sensor is not easy.

Therefore the product realization 8 – channel high – voltage logic and logic low voltage bi-directional transformations embodiment Ax and Bxbi-directional conversion between the two.

How to Use?

In the case of translating between 3.3V and 5V system:

1. VCCA/VA connects to the 3.3V power supply
2. VCCB/VB connects to the 5V power supply
3. GND connects to power negative pole respectively, the two power supply should be common-grounded with each other
4. When Ax has TTL 3.3V input, Bx will get TTL 5V output
5. When Bx has TTL 5V input, Ax will get TTL 3.3V output
6. NO direction control required CityTech BD 

Features :

1. VCCA Raspberry 3.3 V
2. 8 channels bidirectional voltage translation between different logic level, translate between Ax and Bx automatically
3. 4 pairs of power supply interfaces, supports more situation
4. Use tantalum capacitors for power filter, provides more stability
5. VCCB 5V power supply (can be an external 5V power supply)
6. GND connect the negative pole CityTech BD
