8 digit bi-directional 3.3V-5V/5V-3.3V logic level converter board.
It can bidirectionally transfer with 8 channels between high logic voltage and low logic voltage.
VCCA side voltage range: 1.2V-3.6V; VCCB side voltage range: 1.65v-5.5v
Serial communication interface is compatible with UART/IIC/SPI port, which is easy to connect.
Widely used in the communication between 5V SCM and 3.3V device, 3.3V SCM and 5V device. It can also apply in the level conversion between MCU and SD card, MCU and iic/spi serial port devices.
