Level shifter
A bi-directional level shifter board allows communication between 5V and 3.3V devices, i.e. different logic levels. The design is heavily influenced by Ada Fruit level shifter and is based on BSS138 MOSFET (the datasheet contains all the information on how exactly does this board work). The level shifter can work with up to 4 pins.
Do not connect or disconnect connectors while power is ON. All adjustments must be done ONLY when power is OFF.
