i2c / SPI character LCD backpack - STEMMA QT / Qwiic Spedizione:2-4 Settimane The Arduino code used inCharacter LCDs are a fun and easy way to have your microcontroller project talk back to you. They are also common, and easy to get, available in tons of colors and sizes. We've written tutorials on using character LCDs with an Arduino (or similar microcontroller) but find that the number of pins necessary to control the LCD can be restrictive, especially with ambitious projects. We wanted to make a 'backpack' (add on circuit) that would reduce the
