The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the ‘HV’ pin, low voltage (3.3V for example) to ‘LV’, and ground from the system to the ‘GND’ pin.
Features
Comes with 3.3V voltage, with power indicator Power input with anti-reverse protection, and can not provide more than 150mA of current.
To achieve direct serial 5V and 3.3V level communication.
The maximum stable communication baud rate 28800bps.
Can achieve UART, IIC, 1-wire, SPI and other bus signals 3V-5V level of the two-way conversion.
