Logic Level Shifter 4 Channel

A 2-way bi-directional 10-pin logic level converter board allows for safe communication between devices that operate at different logic levels, specifically 3.3V and 5V. These boards are essential when interfacing microcontrollers, sensors, and other peripherals that require different voltage levels to avoid damaging components due to mismatched voltages.

Key Features

1. Voltage Compatibility: Supports 3.3V and 5V logic on separate sides, enabling smooth communication between devices operating at these two voltage levels.
2. 10 Channels: With 10 bi-directional channels, the board can handle multiple signals simultaneously, making it ideal for complex projects with several data lines.
3. Automatic Direction Sensing: Each channel operates independently and automatically detects the direction of the signal, enabling seamless bi-directional communication without extra control signals.
4. Low Power Consumption: Efficiently manages power, requiring minimal additional current from the connected devices.
5. Pull-up Resistors: Often includes onboard pull-up resistors for stable signal transition; some models may offer adjustable or removable resistors for flexibility.
6. Easy Integration: Standard 10-pin headers make the board compatible with breadboards and jumper wires, simplifying connection to other boards or circuits.

Typical Applications

1. Microcontroller Interfacing: Safely connects 5V microcontrollers (like Arduino) to 3.3V sensors or modules (such as ESP32, OLED displays, or GPS modules).
2. Mixed Voltage Systems: Ideal for projects with components running on different voltages, allowing seamless data transfer.
3. Data Communication Protocols: Suitable for various protocols, including I2C, SPI, UART, and GPIO, across different voltage domains.

These boards provide a reliable solution for complex, mixed-voltage projects by protecting sensitive components while maintaining efficient and high-speed data communication between devices.
