Voltage Compatibility: Steps down 5V signals to 3.3V and steps up 3.3V to 5V. It is also widely compatible with 1.8V and 2.8V devices.
Channel Capacity: Features two independent, high-speed channels suitable for protocols like I2C (SDA/SCL) and UART (TX/RX).
Breadboard-Friendly: Compact in size and designed with standard pin spacing for direct mounting onto a breadboard.Simple Wiring: Requires both the high-voltage 5V and low-voltage 3.3V sources to be connected to the board, alongside a common ground.
Dimensions 15 x 15 x 2mm
Weight 2g
APPLICATION
TTL Logic Level Converter
Bidirectional Logic Level Conversion
I2C Sensor Integration: Level shifts the Serial Data (SDA) and Serial Clock (SCL) lines. This allows you to connect 5V systems (like a classic Arduino Uno) to low-voltage sensors (like modern temperature or IMU chips).
UART Serial Communication: Converts Transmit (TX) and Receive (RX) lines so a 3.3V device (e.g., a Raspberry Pi) or wireless module (e.g., ESP8266/ESP32) can communicate with a 5V MCU without frying its pins.
Legacy Component Upgrades: Lets you integrate new 3.3V shields and expansion boards into older 5V mainboards, or vice versa, over standard two-wire digital buses.
General Purpose 2-Wire Digital Bus: Handles various 2-wire bidirectional communication buses like 1-Wire, ensuring voltage domains remain isolated.
