If you've ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The 8-channel Bi-directional Logic Level Converter is a small device that safely steps down 5V signals to 3.3V AND steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices. Each level converter has the capability of converting 8 pins on the high side to 8 pins on the low side..
The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. Connect your low voltage source to the VA pin and use the A1-A8 pins to connect your 1.2V-3.6V device. Connect your high voltage source to the VB pin and use the B1-B8 pins to connect your 1.65V-5.5V device. Connect ground from the system to the 'GND' pin.
