Description:If you’ve ever tried to connect a 3.3V
device to a 5V system, you know what a challenge it can be. The CJMCU
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. What really
separates this Logic level converter from our previous versions is that
you can successfully set your high and low voltages and step up and down
between them safely on the same channel. Each level converter has the
capability of converting 4 pins on the high side to 4 pins on the low
side with two inputs and two outputs provided for each 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. High voltage (5V for example) to the ‘HV’ pin, low voltage
(3.3V for example) to ‘LV’, and ground from the system to the ‘GND’ pin. |
