Good value but pins are tight
The module works as advertised. My only complaint is that the header pins were a bit tight to solder, but once connected it works great.

Essential module for mixed voltage systems
If you are working with both 3.3V and 5V logic, this is a must-have. Bidirectional shifting works flawlessly on the SDA and SCL lines.

Does the job
Solid little board. I wish it came with male headers included in the package, but otherwise no complaints about performance.

Fast delivery and product as described
Arrived quickly and was well packaged. Tested it on an Arduino Uno and a 3.3V OLED display without any issues.

Works perfectly for ESP32 projects
I needed to interface a 5V sensor with my ESP32 and this module solved the voltage mismatch issue immediately. Stable communication and compact size.
Q: Does it require external power supply?
A: No, the module is powered directly through the I²C bus lines connected to your microcontroller and sensor.
Q: Can I use this module for UART communication?
A: This module is specifically designed for I²C buses. While it might work for UART, we recommend a dedicated UART level shifter for best results.
Q: Is this level shifter bidirectional?
A: Yes, this module supports bidirectional voltage level shifting suitable for I²C communication.
Q: What is the maximum clock frequency supported?
A: It supports standard I²C frequencies up to 400kHz, which covers most common sensor applications.
Q: Is this compatible with 5V Arduino Uno?
A: Yes, it is fully compatible with 5V boards like the Arduino Uno when interfacing with 3.3V devices.
