All about the product
2-way logic voltage converter 1.2-5.5V. Have you ever encountered the problem that the 5V logic signal levels between the Arduino and a 3.3V sensor or other module do not match? This converter is designed to solve this very problem. Although this can be done using a voltage divider, as the signal frequency increases, such a solution can cause difficult-to-detect problems that will not occur with this module. This one stands out from other logic converters in that the signal conversion is bidirectional, so you can use it to both send and receive signals, which is what makes it superior to conventional logic converters. The converter automatically detects the direction of the signal.
Note: When using the converter for I2C communication, you must use at least 50 kOhm pull-up resistors, as with lower resistance, the converter may incorrectly recognize the signal direction. Arduino and AVR microcontrollers already have 100 kOhm resistors installed, so there should be no problems with them.
This module is intended for switching logic signals, so it is not advisable to try to power higher-power components, such as LED lights, with it.
Technical data:
- Adjustable voltage levels: 1.2-5.5V DC
- 8 channels
- Two-way signal exchange
