If you have ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The logic level converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side with two inputs and two outputs provided for each side.
The level converter is straightforward to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the “HV” pin, low voltage (3.3V for example) to “LV”, and ground from the system to the “GND” pin.
These are 4 Channel devices (works great for I2C or SPI) and will work with all microcontrollers, Arduino, Raspberry Pi, Intel Edison, etc. Use this module to connect two devices of different digital voltage levels. For example: connecting an Arduino (5V device) to an ESP8266 (3.3V device).
The Level Converter comes complete with header pins and can be used directly on a breadboard.
- Convert 4 pins on the high side to 4 pins on the low side or vice versa
- Power from two voltage sources (high and low); high voltage goes to the HV pin and low voltage to the LV pin
- Pinout labeled on modules

- Weight: 1.2g (0.04oz)
- Mutual transform between 5V TTL and 3.3V TTL
- Four channels of logic and high voltage low voltage logic can two-way transform
- Portable and lightness, with 2 rows 6 pin contact pins
- Level Converter- 4 Channel Compatible with the bread plate, can be used directly put on the breadboard
- 4 Channel Module (great for I2C or SPI) and will work with all microcontrollers, Arduino, Raspberry Pi, Intel Edison, NXP Mbed
The board has the following I/O connections:
- HV = High voltage. Must be higher voltage than LV. Typically tied to 5V
- LV = Low voltage. Must be lower voltage than HV. Typically tied to 3.3V
- GND = Ground (x2). Can be used to pass a ground between the two different voltage circuits
- HV1 / LV1 = Channel 1
- HV2 / LV2 = Channel 2
- HV3 / LV3 = Channel 3
- HV4 / LV4 = Channel 4
How to use:
- High voltage (5V for example) to the HV pin
- Low voltage (3.3V for example) to LV
- Ground from the system to the GND pin.
- 1 x 4 Channel Logic Level Converter
- 2 x male connector
