Question about the LED color on Crazyflie

Post by chingchi »

Hi,

I would like to know if the color of BLUE LED on the Crazyflie can be changed into RED/GREEN or not?
I didn't find any similar question in the post.

Best regards,

Hi,

After reviewing the schematic of crazyflie 2.0, I find that there are some LED diodes labelled with its color, such as BLUE_LED and RG_LED in the attached pictures.
So, we probably can't change the color of BLUE LED into RED or GREEN:(

Best regards,

Hi,

As you noticed the Blue LEDs are only blue so it will not be possible to change their color using only Software.

By doing some soldering work you should be able to change the color of the blue LED, thought these LEDs only have 1 color so you will only be able to change them to red or green. This soldering work would not be very easy so I would not recommend it if you are not experienced in SMD reworking.
