Description: This board is made to handle the mismatch between the digital logic voltage level of the Raspberry Pi and the LED matrix. Digital logic is typically at either 3.3V or 5V. The GPIO pins on the Raspberry Pi will output at the 3.3V logic, and the LED matrix is made to read at 5V digital logic levels. In order to have these signals make sense to each other we use a device called a logic shifter, which will take the 3.3V signals and turn them into 5V signals.
