1 cái 4 kênh IIC I2C mạch chuyển đổi Mức logic Bi-directional mô-đun 5V đến 3.3V

If you've ever tried to connect a 3.3V device to a 5V system, you know how challenging this can be. The bidirectional logic level converter is a small device, which can safely reduce the voltage of 5V signal to 3.3V and simultaneously increase the voltage of 3.3V to 5V. This level converter is also suitable for 2.8V and 1.8V devices. The real difference between this logic level converter and our previous version is that you can successfully set high voltage and low voltage, and safely boost and reduce voltage between them on the same channel. Each level converter can convert 4 pins on the high side to 4 pins on the low side, and provide two inputs and two outputs on each side.
The level converter is very easy to use. The board needs to be powered by two voltage sources (high voltage and low voltage) used by your system. High voltage (e.g. 5V) is connected to HV 'pin, low voltage (e.g. 3.3V) is connected to LV', and system ground is connected to GND 'pin.
