After purchasing an open-source product that is not electrical level compatible, you may find that your sensor cannot work normally or even is easy to be damaged because the level of the sensor and your controller are not compatible. Apart from the poor experience you encountered, this also causes economic losses. In order to solve this problem, DFRobot launched a level conversion module with strong level compatibility and fast signal conversion speed.
This 8-bit non-inverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. VCCA must be less than or equal to VCCB. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for low-voltage bidirectional translation between any of the 1.2V, 1.8-V, 2.5-V, 3.3-V, and 5V voltage nodes. It can automatically track the power supply voltage and its conversion speed can reach up to 60Mbps in push-pull applications. The module can be used in the level conversion of communication protocols such as I2C, UART, SPI, and OneWire.

Plain-language definitions for the technical terms used above.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
