The module allows you to exchange data between systems that use voltage levels ranging from 3.3 V to 5.5 V. Operates in both directions simultaneously, for example, reduces the voltage of 5 V to 3.3 V and raises 3.3 V to 5 V at the same time. This feature is useful in bidirectional communication protocols, for example, the SPI in full duplex mode. The converter has 8 channels.
Specification of Bidirectional Logic Level Conversion Module:
- Supply voltage: from 3.3 V to 5.5 V
- Number of channels: 8
- Dimensions: 37 x 32 mm
- Interface: I2C
Connection example:
In the case of conversion between 3.3 V and 5 V, you must:.
- Pin VCCA/VA connect to power supply 3.3 V
- Pin VCCB/VB to connect to power supply 5 V
- GND connect to ground. Please note that the ground of the entire system was connected.
- When the Ax will signal with a voltage of 3.3 V, it will appear on the Bx signal 5 in
- When the Ax will signal with a voltage of 5 Volts, it will appear on the Bx signal 3.3 V
- There is no need to control the direction
