Thanks, Gerald. Well, here it says for this module: Red Vf: 1.8 to 2.1V Green Vf: 3.0 to 3.2V Blue Vf: 3.0 to 3.2V https://sites.google.com/site/summerfuelrobots/arduino-sensor-tutorials/3-color-rgb-led-module
So in theory I could connect it to BBB's pwm pins (3.3v?) after all but with 3 x 1k ohm resistors? It won't be bright, but it will be safe (for BBB) and it will work?
