General description The bidirectional logic level converter is a device that safely downgrades 5V signals to 3.3V while simultaneously boosting 3.3V to 5V. This module works with 2.8V and 1.8V devices, allowing bidirectional transmission between high-side and low-side logic voltages across 4 channels. Each converter can handle 4 pins on the high side and 4 pins on the low side, featuring two inputs and two outputs for each side. Technical specifications Channels: 4 High-side voltage: 5V Low-side voltage: 3.3V Compatible with: 2.8V and 1.8V devices Measurement allowed error: +/- 1-3 cm Other information Color: Blue Material: Plastic Package Contents: 60 x 4-Channel I2C Bidirectional Logic Level Converter Module Note: Light reflection and different displays may cause the color of the item to differ slightly from the actual product.
