Review on Adafruit Bi Color 24 Bar Bargraph Backpack by Kimberly Brown

I am using this for a Lego Turbine IoT project. Bar graph works fine, no problems connecting to Raspberry Pi Zero following Adafruit's instructions. You can control the color of each LED or all at once with a single command. I wish it was green/yellow/red, but it's more of a green/orange/red. The only negative I can think of is the blinking: the built in blink command is all or nothing, can't control the blinking of individual LEDs unless you create your own blinking function. Even the "fastest" flicker is still a bit slow in my opinion.
