1. Introduction
The Cylewet CYT1082 is an 8-channel bi-directional logic level converter module designed to facilitate communication between devices operating at different voltage levels. This module enables seamless and safe signal transfer between high logic voltage (e.g., 5V) and low logic voltage (e.g., 3.3V) systems, making it suitable for various microcontroller projects, including those involving Arduino platforms.
2. Package Contents
Each package contains the following components:
- 5 × 8 Channel Logic Level Converter Bi-directional 3.3V to 5V TTL Shifter Module
- 5 × Single Row Pin Header (10 pins)

3. Product Overview
The CYT1082 module features 8 independent channels for voltage level translation. It is compact in size, measuring approximately 4.1 × 1.8 cm (1.6 × 0.7 inches), making it suitable for space-constrained applications. The module is designed for bi-directional signal transfer, allowing data to flow in both directions between the high voltage (HV) and low voltage (LV) sides.

4. Setup and Installation
4.1 Pinout Description
The module has two sets of pins: one for the High Voltage (HV) side and one for the Low Voltage (LV) side. Each side includes power supply pins and 8 data channels.

| Pin Label | Description |
|---|---|
| HV | High Voltage supply input (e.g., 5V) |
| LV | Low Voltage supply input (e.g., 3.3V) |
| GND | Ground connection (common ground for both HV and LV systems) |
| HU1-HU8 | High Voltage side data channels (8 channels) |
| LU1-LU8 | Low Voltage side data channels (8 channels) |
4.2 Connection Instructions
- Connect Power: Connect the high voltage power supply (e.g., 5V) to the HV pin. Connect the low voltage power supply (e.g., 3.3V) to the LV pin.
- Connect Ground: Connect the common ground of both your high voltage and low voltage systems to the GND pin on the module. This is crucial for proper operation.
- Connect Data Channels: Connect the high voltage side signals to the HU1-HU8 pins and the low voltage side signals to the corresponding LU1-LU8 pins. The module will automatically translate the logic levels bi-directionally.
Example: To convert a 3.3V signal to 5V, connect the 3.3V signal source to an LUx pin, and the 5V device input to the corresponding HUx pin. For 5V to 3.3V conversion, connect the 5V signal source to an HUx pin, and the 3.3V device input to the corresponding LUx pin.
5. Operating Instructions
Once properly connected, the Cylewet CYT1082 module operates automatically. It detects the voltage levels on the HV and LV sides and performs the necessary translation for each of the 8 channels independently. No additional configuration or software is required for its basic function. Ensure that the voltage supplied to the HV and LV pins matches the logic levels of the devices you are connecting.
