Product Description
If you’ve ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be? A bi-directional Level Converter- 4 Channel is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices. What really separates this Logic level converter from our previous versions is that you can successful
How to use:
- High voltage (5V for example) to the ‘HV’ pin
- Low voltage (3.3V for example) to ‘LV’
- Gound from the system to the ‘GND’ pin.
Specifications and Features:
- 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 ChannelCompatible 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
Applications
-
I2C Level Shifting: Bridging $5\text{V}$ microcontrollers to $3.3\text{V}$ $\text{I}^2\text{C}$ devices (such as OLED screens, BMP280 barometric sensors, or MPU6050 gyroscopes).
-
UART Serial Communication: Safe serial debugging between $5\text{V}$ USB-to-UART converters and $3.3\text{V}$ ESP8266/ESP32 chips.
-
Mixed-Voltage SPI Bus: Stepping up/down MISO, MOSI, SCK, and CS lines for SD card modules or high-speed displays.
Compatibility
-
5V Devices: Fully compatible with classic microcontrollers like Arduino Uno, Nano, Mega, and standard $5\text{V}$ logic systems.
-
3.3V Devices: Safe for delicate modern hardware including ESP32, ESP8266, Raspberry Pi, STM32, and $3.3\text{V}$ sensors.
-
Note: While most commonly used for $5\text{V}$ to $3.3\text{V}$ translation, it can also safely step down/up between other custom ranges such as $2.8\text{V}$ and $1.8\text{V}$ as long as the higher reference voltage is connected to HV.
