2 Channel Logic Level Converter 3.3V 5V TTL
This bi-directional logic level converter is designed to safely translate signals between different voltage levels. It can convert signals both ways, such as from 5V to 3.3V and vice versa, or from 2.8V to 1.8V and back.
The converter features four channels, each capable of switching between two voltage levels on the same line. Each channel has two inputs and two outputs, one for the high voltage side and one for the low voltage side, making it versatile and easy to use.
To operate the converter, connect it to the two voltage sources used by your system. For example, if your system uses 5V and 3.3V, connect the 5V source to the ‘HV’ pin and the 3.3V source to the ‘LV’ pin. Also, connect the system’s ground to the ‘GND’ pin to complete the setup.

2 Channel Logic Level Converter 3.3V 5V TTL Overview
This 2 Channel Logic Level Converter safely translates digital signals between 3.3V and 5V TTL voltage domains. It is ideal for interfacing 5V microcontrollers like Arduino with 3.3V devices such as ESP8266, ensuring reliable bi-directional data transfer without damaging components.
Key Features of 2 Channel Logic Level Converter 3.3V 5V TTL
- Bi-directional conversion between 3.3V and 5V TTL logic levels
- Two independent channels, each with HV (high voltage) and LV (low voltage) pins
- Plastic and metal construction for lightweight durability
- Comes with 2×6 unsoldered pin headers for custom breadboard or PCB integration
- Compact footprint allows direct insertion into solderless breadboards
- Genuine product with fast shipping from Zbotic.in
Applications and Use Cases
- Connecting 5V Arduino boards to 3.3V modules like ESP8266 or nRF24L01
- Level shifting I2C signals (SDA/SCL) between different voltage domains
- Safely interfacing SPI devices (MOSI/MISO) operating at lower voltages
- TTL serial communication (UART) between microcontrollers and sensors
- Integrating 3.3V digital sensors with 5V development kits in robotics or automation
- Prototyping mixed-voltage circuits on a solderless breadboard
How to Use 2 Channel Logic Level Converter 3.3V 5V TTL
Solder the provided 2×6 pin headers (or wires) to the board and plug it into your breadboard. Connect the 5V supply to the HV pin, the 3.3V supply to the LV pin, and tie all grounds to GND. Feed a digital signal into HVx to receive a 3.3V output on LVx, or vice versa, allowing seamless bi-directional level shifting.

Frequently Asked Questions
How do I connect this converter between an Arduino and an ESP8266?
Connect Arduino 5V to the HV pin and ESP8266 3.3V to the LV pin. Share a common ground on GND. Route Arduino TX to HV1, and take the shifted LV1 output to ESP RX; similarly, route ESP TX to LV2 and take HV2 to Arduino RX.
Do I need to solder the headers before using it on a breadboard?
Yes. The module ships with 2×6 unsoldered pin headers so you can position it precisely. Solder the headers or wires, then plug the board directly into your breadboard for secure connections.
Can I use this module for I2C communication?
Absolutely. Assign one channel to SDA and the other to SCL. The bi-directional MOSFET design handles open-drain I2C lines, letting you interface 5V masters with 3.3V peripherals without extra pull-ups.
