Hi RustySpoons, Indeed I am interested ! Using the i2c pins does free up quite some pins, and since I am planning the GPIO pin usage for my project(s) this does simplify. My question , Does the backpack allow you to do parallel output to the LCD only , or would it allow you to get info back from buttons too ? The reason is I spotted quite a lot of cheap 1602 displays with I2C combined , and 1602 displays with buttons. Ideally I would combine the usage of the buttons and the I2C communication, if there are options. BTW Tibali, Great work ! I will order some missing parts and experiment with your Slimmer setup. Probably adding a second rotary controller for dedicated volume-up -down and pause/play.
