Overview:
If
you've ever tried to connect a 3.3V device to a 5V system, you know what
a challenge it can be. The SparkFun logic level converter is a small device
that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V. This
level converter also works with 2.8V and 1.8V devices. Each level converter
has the capability of converting 4 pins on the high side to 4 pins on the
low side. Two inputs and two outputs are provided for each side.
Bread
board friendly! Can be used with normal serial, I2C, SPI, and any other
digital signal. Does not work with an analog signal.
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 (2.8V
for example) to 'LV', and ground from the system to the 'GND' pin.
Pins
are labeled as Inputs and Outputs. These are relative to the board. A digital
one going into the RXI pin on the 5V side will show up on the RXO pin on
the 3.3V side as 3.3V. A digital one going into the TXI pin on the 3.3V
side will show up on the TXO pin on the 5V side as 5V.
