Features:
· The bidirectional logic level converter is a small device that can safely step down 5V signals to 3.3V and can also boost 3.3V to 5V.
· This level shifter board combines the ease of use of the bidirectional BSS138 and the I2C compatible FET design, following the NXP application instructions.
· Each level shifter can convert the 4 pins on the high side into 4 pins on the low side, and provide input and two outputs for each side
· This level shifter is also suitable for 2.8V and 1.8V devices, and can perform 4-channel bidirectional conversion between high logic voltage and low logic voltage.
· Used with I2C, but it is also suitable for TTL serial, slow speed SPI and any other unidirectional and bidirectional digital interfaces. Does not work with an analog signal.

Specification:
Size：1.52*1.27cm(0.6*0.5)
It's compatible with breadboard and can be directly plugged into the breadboard for use, which is convenient for applications such arduino
Voltage input:
The pins marked HV, LV and two GND provide high and low voltage references for the circuit board, and a stable regulated voltage needs to be provided for these two inputs.
The voltage supplied to the HV and GND inputs should be higher than the voltage supplied to the LV side. For example, if you connect from 5V to 3.3V, the voltage on the HV pin should be 5V and the voltage on LV should be 3.3V.
Data channel:
There are four independent data channels on the level shifter board, and each channel can convert data back and forth between high voltage and low voltage. These pins are labeled HV1, LV1, HV2, LV2, HV3, LV3, HV4, and LV4.
The number at the end of each label specifies the channel of the pin, and the HV or LV prefix determines whether it is on the high side or the low side of the channel.
