Key Features of 4 channel logic level converter
- True bi-directional conversion - signals shift seamlessly in both directions on all 4 channels without any configuration
- Protect expensive components - prevent damage when connecting 3.3V devices like Raspberry Pi, ESP32, or BME280 sensors to 5V Arduino boards
- Multi-protocol support - works with I2C (using 2 channels for SDA/SCL), SPI (using 3-4 channels for MOSI/MISO/SCK/CS), UART, and general GPIO signals
- Ultra-compact design - tiny footprint fits easily on breadboards and inside enclosures without consuming valuable space
- BSS138 MOSFET-based architecture - proven, reliable level shifting with integrated pull-up resistors for clean signal transitions
- Wide voltage compatibility - low side supports 1.8V to 3.3V, high side supports 3.3V to 5V, covering virtually all common microcontroller and sensor voltages
Perfect For
- Arduino + Raspberry Pi Communication: Bridge the 5V Arduino and 3.3V Raspberry Pi over I2C or SPI for hybrid projects combining real-time control with Linux computing power.
- ESP32/ESP8266 Sensor Networks: Safely connect 5V sensors, OLED displays, and SD card modules to your 3.3V ESP32 or ESP8266 for IoT and home automation systems.
- 3.3V Sensor Integration with Arduino Uno: Interface popular 3.3V sensors like BME280, BMP180, MPU6050, or ADXL345 with your 5V Arduino without risking sensor damage.
- UART Serial Communication: Level-shift TX/RX lines between different voltage microcontrollers, GPS modules, Bluetooth modules (HC-05), or GSM modules safely.
- SPI Display & Storage Projects: Connect 3.3V TFT displays, e-paper screens, or microSD card breakout boards to 5V microcontrollers with proper signal integrity.
- Multi-Microcontroller Systems: Build complex projects using mixed-voltage microcontrollers (STM32, Teensy, Arduino, Raspberry Pi Pico) communicating reliably over shared buses.
- Educational Electronics Lab: Teach students about voltage domains, digital logic levels, and proper interfacing practices - a fundamental concept in embedded systems design.
How to Connect
- Step 1: Connect your low-voltage supply (e.g., 3.3V from your ESP32 or Raspberry Pi) to the LV pin on the module.
- Step 2: Connect your high-voltage supply (e.g., 5V from your Arduino) to the HV pin on the module.
- Step 3: Connect GND from both devices to the GND pins on the module - common ground is essential.
- Step 4:
