I have bought similar lights from other seller and they were fine, but this is a piece of junk! The yellow light is extremely weak and the green one may burn out your device. I have measured resistors: 220 Ω to red (OK), 4.6 kΩ to yellow (too much), less than 1 Ω (!) to green (dangerous). The current at 3.3 V is 6 mA to red (OK), 0.3 mA to yellow (that's why it has almost no light) and 53 mA to green (dangerous for microcontrollers). It is absolutely not corresponding to seller's description. Don't attach it to 5 V! Green light is almost burning, lighting as orange. If you want to use this junk, you have to change SMD resistors. One photo is on 3.3 V, other on 5 V (the green is almost burning).
The red LED is too bright, the green LED is bright, the yellow LED is dim. There are resistors on the circuit boards but they do not work properly. I have to put extra resistors in series on the red and green led so that all 3 are equally bright. The supplier does not accept my complaint.
