Essential for any Pi project

If you are working with Raspberry Pi and legacy 5V modules, this is a must-have. It handles the level shifting automatically so you don't have to worry about frying your GPIO pins. Highly recommended.

Reliable and fast shipping

Used this for an SPI display project. Signal integrity is perfect even at higher clock speeds. No noise or dropped packets. The compact size fits nicely in my enclosure.

Solid build, clear labeling

The PCB quality is excellent and the silk screen labeling makes wiring very easy. Took off one star because the headers were not included, but that's a minor inconvenience. Works exactly as described.

Bought five for our lab

We equipped our entire electronics lab with these. They are robust and handle student errors well. No failures so far after months of heavy use. Excellent product for education.

Perfect for mixing 3.3V and 5V sensors

This module solved my voltage mismatch issue instantly. I connected several 5V ultrasonic sensors to my Raspberry Pi without any signal degradation. The bidirectional feature works flawlessly for I2C communication.

Great value for money

For the price, you get 8 channels which is more than enough for most projects. Instructions could be slightly more detailed for beginners, but there are plenty of tutorials online.

5 FAQ

Q: What is the maximum current per channel?

A: The module is designed for logic level signaling, not power delivery. The typical current capacity per channel is around 20mA, suitable for signal lines only.

Q: Is it compatible with 1.8V logic systems?

A: Yes, the low-voltage side supports ranges from 1.8V up to 3.3V, making it compatible with newer microcontrollers that operate at 1.8V logic levels.

Q: Does this module require an external power supply for both voltage rails?

A: Yes, you need to connect both the LV (Low Voltage, e.g., 3.3V) and HV (High Voltage, e.g., 5V) power pins to their respective sources for the module to function correctly.

Q: Are the pin headers pre-soldered?

A: No, the module comes with unsoldered header pins to allow for flexible mounting options. You will need to solder them yourself or use jumper wires directly.

Q: Can I use this for WS2812B LED strips?

A: While technically possible for the data line, this module is optimized for I2C, SPI, and UART signals. For WS2812B, a single logic level shifter or a dedicated driver circuit is often more cost-effective.
