Does the aboy have the ftdi header to easily update the firmware? Do you have pics of the various colors?
There's no FTDI header, but the chip can be removed from its socket and flashed using an Arduino.
The only difference is the LED color. I don't have any photos of the lit LEDs, but this image shows the very subtle color differences.
Bottom row: orange, red, red, yellow.
I can post photos of them lit if you'd like, but it's basically what you'd expect from an LED.
