Logic Level Converter 2-Channel 5V / 3.3V

This module connects controllers with different logic voltages, for example a Raspberry Pi with 3.3 V and an Arduino Uno with 5 V. It has 2 channels, each with one line in both directions and one line from high to low, fits on breadboards and works with protocols such as SPI, serial and I2C as well as with digital signals. Analog signals are not supported.

Recommended alternative with more bidirectional channels: 4-Channel 5V / 3.3V Logic Level Converter or 8-Channel Logic Level Converter TXS0108E

Features:

• TXI and TXO: bidirectional, for I2C route SDA and SCL each via TXI and TXO
• RXI and RXO: from high to low only, voltage divider
• HV and LV must both be supplied with their reference voltage, GND on both sides
• For digital signals only

Application Examples:

• 5 V sensors on ESP8266, ESP32 or Raspberry Pi
• SPI, I2C and serial connections between 3.3 V and 5 V
