This week in our sample pile we have an I2C/SPI character LCD module we're checking out. Although historically 16x2 character displays use a parallel method of addressing - with 4 or 8 bit data input and a write latch - most folks don't want to waste so many pins on such a slow display. So, instead, many now come with I2C interfaces. That makes wiring or routing a lot easier!
Digi-Key stocks a huuuuge range of character displays, let's check out what's available and some things to watch for with voltages, backlights, and polarizer types.
