Description: This is a quad channel level converter which can convert high voltage digital signal to low voltage digital signal and vice versa. When you need to connect 5v microcontroller to 3.3v sensors then this module can be used. It does not work with analog signals, i.e. you can use it for SPI, I2C or any other serial communication but this cannot be used with sensors which outputs analog voltage.

It uses 0805 size 10k resistors and BSS130 FET which can work up to 10v on high side and 1.8v on low side.
