4 WAY UART SPI

4 Way Level Conversion Module 5V To 3.3V 3.3V To 5V IIC UART SPI
Four MOS tube realization four road 3V and 5V level bidirectional conversion,
With anti reverse connection protection, power input is integrated with 3.3VLDO, and can provide a current less than 150mA
With a power indicator
can achieve UART, IIC, 1-wire, SPI etc. bus signal bidirectional conversion, conversion cannot be between different protocols
