UPDATED GUIDE: I2C/SPI LCD Backpack AdafruitLearningSystem #Adafruit @adafruit @BlitzCityDIY

LCDs are a fun and easy way to have your microcontroller project talk back to you. We wanted to make a ‘backpack’ (add-on circuit) that would reduce the number of pins without a lot of expense. By using simple I2C and SPI input/output expanders we have reduced the number of pins (only 2 pins are needed for I2C) while still making it easy to interface with the LCD.

The I2C/SPI LCD Backpack guide has been updated to include the new STEMMA QT version of the LCD backpack. There is a new Pinouts page, updated Fritzing diagrams for CircuitPython and Arduino and new resources on the Downloads page.
