Adafruit 0.56" 4-Digit 7-Segment Display w/I2C Backpack - Blue pwm so you can power quite

so you can power quite a bit without burning out your switch

The  PiTFT got even better with this little primary display for Raspberry Pi in HAT form

Like all real Arduinos

(For RGB we have RGB positive

This is an unassembled kit which means that soldering is required - but it’s very easy and a great introduction to soldering in general
