This is a 8 channel level conversion module two-way conversion between 3.3V and 5V IO access 5V sensor for Raspberry Pi.
It is a 8 channel or 8-bit logic level converter that is great for interfacing sensors or 3.3v logic components with 5v logic level microcontrollers or vice versa. This unit will do the level shifting required to allow these devices to communicate without burning out each other. If you want to convert an analog signal you require an op-amp.
Features:
Features:
- 8 channels bidirectional voltage translation between different logic level, translate between Ax and Bx automatically
- 4 pairs of power supply interfaces, supports more situations
- Use tantalum capacitors for power filter, provides more stability
- Voltage level: 1.8V-6V
- Dimension: 31.6mm x 25.4mm
How to Use
In the case of translating between 3.3V and 5V system:
In the case of translating between 3.3V and 5V system:
- VCCA/VA connects to 3.3V power supply
- VCCB/VB connects to 5V power supply
- GND connects to power negative pole respectively, the two power supply should be common-grounded with each other
- When Ax has TTL 3.3V input, Bx will get TTL 5V output
- When Bx has TTL 5V input, Ax will get TTL 3.3V output
- NO direction control required
